The residual biomass produced in the olive sector is the result of the large quantity of olive groves and olive oil manufacturers that generate byproducts with a potentially high energy content. Until now, the disposal and management of pruning residues and olive oil by-products has generally represented disposal problems which lead to environmental problems rather than opportunities for additional revenue. In this context, this study aimed to define a roadmap for studies in Turkey to untap the potential of olive grove residues and olive oil industry by-products and residues, (i.e., olive tree prunings, olive leaves, olive pomace) that could be used to produce high-added value products in an integrated biorefinery or in a bioenergy power plant. This paper presents a review on recent research on the valorization of olive by-products in line with the circular economy principles and the bioeconomy strategy and presents the literature which applies to design and management of olive biomass supply chains. Main objective is to provide a conceptual framework for developing and deploying an effective bioeconomy utilizing olive prunings and olive oil industry byproducts conducting a preliminary review of the olive oil chain residues in Europe and Turkey comparatively, assessment of technical potentials, biomass supply costs and allocation of biomass collection sites and energy production facilities with different supply chain scenarios. Biomass resource assessment, biomass feedstock supply chain design and management, and logistics optimization require multidisciplinary and interdisciplinary approaches. They need to be carried out properly in order to execute efficient projects in energy generation from biomass and/or extracting bio-commodities in biorefineries. Turkish researchers have adequate research on valorization methods for olive based biomass resources, but their studies are limited on general biomass supply chain design and particularly no research has been conducted for olive biomass resources. Taking all the aforementioned into account, the author proposes to conduct further studies on a biomass energy project including design of a supply chain network for energy valorization of olive grove residues and olive oil industry by-products in line with the common practice and being inspired by the leading countries like Spain and Italy, which will both contribute to circular business concept development and renewable energy capacity increase.
橄榄行业产生的剩余生物质是大量橄榄园和橄榄油制造商产生具有潜在高能量含量的副产品的结果。到目前为止,修剪残留物和橄榄油副产品的处理和管理通常是导致环境问题的处理问题,而不是增加收入的机会。在此背景下,本研究旨在为土耳其的研究确定路线图,以挖掘橄榄林残留物和橄榄油工业副产品和残留物(即橄榄树修剪,橄榄叶,橄榄渣)的潜力,这些残留物可用于生产高附加值产品在综合生物精炼厂或生物能源发电厂。本文根据循环经济原则和生物经济战略对橄榄副产品的价值化研究进行了综述,并介绍了适用于橄榄生物质供应链设计和管理的文献。主要目标是为开发和部署有效的生物经济提供一个概念性框架,利用橄榄修剪和橄榄油工业副产品对欧洲和土耳其的橄榄油链残留物进行初步审查,比较评估技术潜力,生物质供应成本以及不同供应链情景下生物质收集点和能源生产设施的分配。生物质资源评估、生物质原料供应链设计和管理以及物流优化需要多学科和跨学科的方法。它们需要得到适当的执行,以便执行有效的项目,从生物质中产生能源和/或在生物精炼厂中提取生物商品。土耳其研究人员对橄榄基生物质资源的价值化方法进行了充分的研究,但他们的研究仅限于一般的生物质供应链设计,特别是没有对橄榄生物质资源进行研究。综上所述,作者建议进一步研究一个生物质能项目,包括按照惯例设计一个橄榄林残留物和橄榄油工业副产品的能源增值供应链网络,并借鉴西班牙和意大利等领先国家的经验,这将有助于循环商业理念的发展和可再生能源容量的增加。

The rapid growth of the transportation industry and the advance of the e-commerce have opened opportunities for boom delivery services companies. Although, intense competition between shipping companies has obliged many to amend their shipment networks. In this setting, we aim to provide high-quality shipping services for a third-party logistics company in Iran. Currently, in the selected company, one hub is in the west part of Tehran that gives services to all customers. There are some difficulties in shipping services to the eastern part of Tehran city. Therefore, in this paper, we find the location of another hub center to streamline the shipping process. Moreover, to promote our service levels, some Distribution Centers (DCs) are going to be set up. Due to the lack of shipment data like pick up and delivery data, we tried to find the locations of the hub and the DCs based on Tehran population's data. We clustered 122 regions of Tehran based on population, economic index, accessibility to the internet, and the number of business units. Since some remote regions (which are not in the same vicinity) belong to the same cluster, we defined a relative distance criterion to avoid making remote regions in the same cluster. In each cluster, a fixed or movable DC can be set up to service the regions of its cluster. Moreover, to find the best candidate locations for the hub, each zone of Tehran was assessed based on some criteria like land cost, accessibility to the highways, and distance to its nearest bus terminal. Based on these criteria, some zones have been dominated by others, and the remains were considered as candidate locations in a hub location model. By considering the DCs as spokes in a hub and spoke model, the optimal location for the eastern hub establishment was determined.
交通运输业的快速发展和电子商务的发展为快递服务公司的蓬勃发展提供了机会。尽管如此,航运公司之间的激烈竞争迫使许多公司修改其航运网络。在此背景下,我们的目标是为伊朗第三方物流公司提供高质量的航运服务。目前,在选定的公司中,一个中心位于德黑兰西部,为所有客户提供服务。到德黑兰东部的航运服务有一些困难。因此,在本文中,我们找到了另一个枢纽中心的位置,以简化航运过程。此外,为了提高我们的服务水平,我们将建立一些配送中心(dc)。由于缺少提货和发货数据等发货数据,我们试图根据德黑兰人口数据找到枢纽和dc的位置。我们根据人口、经济指数、互联网可及性和商业单位的数量,对德黑兰的122个地区进行了分类。由于一些偏远地区(不在同一附近)属于同一聚类,我们定义了一个相对距离准则,以避免偏远地区在同一聚类中。在每个集群中,可以设置一个固定或移动数据中心,为其集群的区域提供服务。此外,为了找到中心的最佳候选地点,德黑兰的每个区域都根据一些标准进行了评估,如土地成本、高速公路的可达性以及到最近的公交总站的距离。基于这些标准,一些区域已经被其他区域所主导,并且遗骸被认为是枢纽位置模型中的候选位置。在轮辐模型中,将DCs视为轮辐,确定了东部轮毂的最优位置。

A strategy is a plan of action designed to achieve a long-term or general purpose. It is a military term, and its origin goes back to Sun Tzu. Its use in the modern sense coincides with the 1980s. In the increasingly competitive environment in recent years, businesses need to make a difference in the market, increase their profitability, closely follow technological developments, etc. They attach importance to developing their strategies in the corporate sense and in the field of business management strategies. However, it has been determined that enterprises cannot develop in the field of supply chain management strategies, which is one of their functional strategies, especially in the researches. Determining supply chain strategies will enable them to compete in the market, especially in terms of reducing costs, increasing customer experience, adopting innovative approaches or quality. Businesses may choose to compete in only one of these factors, or they may adopt several factors. In this study, a supply chain strategy determination study was carried out in a company that has a very important position in the wood-based panel industry sector and has adopted supply chain management, but where no strategic decisions or projects have been created. SWOT analysis was used in terms of company and supply chain process. Ten (10) supply chain strategies were determined.
战略是为实现长期或一般目的而设计的行动计划。这是一个军事术语,它的起源可以追溯到孙子。它在现代意义上的使用与20世纪80年代一致。在近年来竞争日益激烈的环境中,企业需要在市场上有所作为,提高盈利能力,密切关注技术发展等。他们重视在企业意识和企业管理战略领域发展自己的战略。然而,供应链管理战略作为企业的职能战略之一,已经被确定为企业无法在供应链管理战略领域发展,尤其是在研究中。确定供应链战略将使他们能够在市场上竞争,特别是在降低成本,增加客户体验,采用创新方法或质量方面。企业可以选择只在其中一个因素中竞争,也可以采用几个因素。在本研究中,供应链战略确定研究是在一家公司进行的,该公司在人造板行业中占有非常重要的地位,并采用了供应链管理,但没有战略决策或项目已经创建。对公司和供应链流程进行SWOT分析。确定了十(10)种供应链策略。

Parcel Locker Applications in Turkey 包裹寄存柜在土耳其的应用
Pub Date : 2023-01-12 DOI: 10.20854/bujse.1219275
Kutay Akdoğan, Eren Özceylan
Alternative delivery applications are gaining popularity today, and parcel lockers are differentiated from others as they offer different delivery location options to customers. One of the biggest problems faced by courier companies today is that customers are not always available at the place of delivery during delivery. This leads to an increase in failed deliveries that place an extra burden on last mile operations, not only in terms of cost, but also in terms of environmental concerns. One of the effective methods to deal with this problem is parcel lockers. Parcel lockers and related concepts are currently used in various countries worldwide, and in some countries, their installation and use are supported by the government. Parcel lockers not only help logistics companies navigate their operations and costs, but also give the customer the power of choice. Therefore, it is considered necessary to investigate the parcel locker applications in Turkey. This paper intends to present the current state of parcel lockers in Turkey, the companies providing the service, their profiles, and their plans to provide beneficial knowledge to academia and industry.
如今,替代递送应用程序越来越受欢迎,包裹寄存器与其他应用程序不同,因为它们为客户提供不同的递送位置选择。如今,快递公司面临的最大问题之一是,在送货过程中,客户并不总是在送货地点。这导致了交货失败的增加,给最后一英里的运营带来了额外的负担,不仅在成本方面,而且在环境问题方面。解决这一问题的有效方法之一是包裹储物柜。包裹储物柜和相关的概念目前在世界各国都在使用,在一些国家,它们的安装和使用是由政府支持的。包裹储物柜不仅可以帮助物流公司控制运营和成本,还可以给客户选择的权力。因此,认为有必要调查包裹寄存柜在土耳其的应用。本文打算介绍包裹储物柜在土耳其,提供服务的公司,他们的档案,和他们的计划,以提供有益的知识,学术界和工业界的现状。

In the developing and changing world, the field of technology hosts many innovations. Supply chain management has also evolved in the light of technological developments and incorporated the concept of agility. Agile supply chain is the ability to respond quickly to unexpected changes in demand and supply. As supply chains compete in a rapidly changing and growing market, the agility of the supply chain provides a significant competitive advantage to firms. An agile supply chain has the ability to respond flexibly and quickly to demands and problems. It benefits companies by adopting the right product, the right customer, the right transportation, and the right supply system. In this study, it was aimed to evaluate the agile methods used in the supply chain management processes, and for this purpose, a multi-criteria model consisting of 12 criteria and 9 alternatives was proposed. This proposed model was solved with two-stage multi-criteria solution techniques, and in the first stage of the solution, criterion weights were calculated with the SWARA method, while the evaluation and ranking of alternative agile methods were carried out with the WASPAS method. The application results are presented in the study, so that the most appropriate agile method methodology to be used in supply chain management was determined.
在不断发展和变化的世界中,技术领域承载着许多创新。供应链管理也随着技术的发展而发展,并融入了敏捷性的概念。敏捷供应链是快速响应需求和供应的意外变化的能力。随着供应链在快速变化和增长的市场中竞争,供应链的敏捷性为企业提供了显著的竞争优势。敏捷供应链具有灵活快速地响应需求和问题的能力。它通过采用正确的产品、正确的客户、正确的运输和正确的供应系统使公司受益。在本研究中,旨在评估敏捷方法在供应链管理过程中的应用,为此,提出了一个由12个标准和9个备选方案组成的多准则模型。该模型采用两阶段多准则求解技术进行求解,第一阶段采用SWARA方法计算准则权重,采用WASPAS方法对备选敏捷方法进行评价和排序。给出了敏捷方法在供应链管理中的应用结果,从而确定了最适合于供应链管理的敏捷方法方法学。

EFFECTIVE SOLUTIONS FOR COMMON PROBLEMS OF ARTIFICIAL POTENTIAL FIELD BASED PATH PLANNING ALGORITHMS FOR MOBILE ROBOTS 基于人工势场的移动机器人路径规划算法中常见问题的有效解决
Pub Date : 2022-12-24 DOI: 10.20854/bujse.1214752

Abstract Autonomous Path Planning (APP) capability is one of the main factors determining the autonomous level of a mobile robot. Although different methods are used for APP in the literature, the path planning approach based on Artificial Potential Fields (APF) has a very common usage area with its modeling ease and computational performance. APF-based APP, which is a grid-based path planning approach, is usually performed by combining a repulsive and attractive component that models many basic motions with a certain equation and calculating the gradient of this potential field to obtain the vector field. In this study, the basic models used for APF-based APP are examined, and how they are realized and how the resultant potential field is produced are mentioned. Although APF-based APP approaches have advantages, they also have problems such as local minimum, obstacles positioned too close, oscillation, and targets positioned too close to obstacles. Within the scope of the study, these problems were defined one by one and the approaches suggested in the literature for the solution of these problems were mentioned in detail. As a result, it has been seen that to obtain an effective APF-based APP solution, it is necessary to generate a convolutional vector field, limit the fundamental potential fields with exponential functions, use virtual potential fields and perform models with harmonic functions.
自主路径规划(APP)能力是决定移动机器人自主水平的主要因素之一。虽然文献中应用的路径规划方法多种多样,但基于人工势场(Artificial Potential Fields, APF)的路径规划方法以其易于建模和计算性能广受欢迎。基于apf的APP是一种基于网格的路径规划方法,通常将一个排斥和吸引分量结合起来,用一定的方程对许多基本运动进行建模,并计算该势场的梯度,从而得到矢量场。本文考察了基于apf的APP所使用的基本模型,并介绍了它们是如何实现的,以及最终势场是如何产生的。基于apf的APP方法虽然有优势,但也存在局部最小值、障碍物定位过近、振荡、目标定位过于靠近障碍物等问题。在研究范围内,对这些问题进行了逐一界定,并详细介绍了文献中提出的解决这些问题的方法。由此可见,为了获得有效的基于apf的APP解决方案,需要生成卷积向量场,用指数函数限制基势场,使用虚势场,用调和函数进行建模。

ŞİMDİ AL SONRA ÖDE KREDİ SİSTEMİ ÜZERİNE BİR DAVRANIŞ VE SKORLAMA ANALİZİ
Pub Date : 2022-12-15 DOI: 10.20854/bujse.1217602
Zeynep Nur Sandikci, Ediz Şaykol
Finansal teknolojilerin, 4. Endüstri devriminin tetiklemesiyle hızlı gelişimi, tüketicilerin harcama davranışlarında değişikliklere neden olmuştur. Bu değişime uygun olarak, Şimdi al sonra öde (BNPL) sistemi değişen müşteri ihtiyaçları sonrası ortaya çıkan yeni bir ödeme sistemi teknolojisidir. BNPL nakit borç vermeye değil, ürün ya da hizmet almaya yönelik bir yöntemdir. E-ticaret sitesinde ya da fiziki mağazada beğenilen ürün ya da hizmetin ödemesini uygun kişilere hızlıca sağlamak esastır. Örneğin bir tatil paketi alımında tur şirketleri BNPL yöntemi ile tüketiciye kredi kartı limitinden düşmeden ya da kredi kullandırmadan ödeme yapma olanağı sağlayabilmektedir. Ürün sahibi işletme BNPL kredisini bankalar aracılığı ile ve yapacağı ikili anlaşmalar doğrultusunda sağlamaktadır. Müşteri ise anlaşmalı bankaların sistemlerinden firma ismi ve ürün kategorisi belirterek BNPL kredi talebinde bulunmaktadır. Eş zamanlı olarak ilgili banka da müşterinin BNPL kredisi için uygun olup olmadığını belirlemek için güvenilirlik skorlaması yapmaktadır ve yüksek skoru olan müşteriye BNPL kullandırtmaktadır. Klasik krediden ayrılan en önemli noktalardan biri hedef müşteri kitlesidir. Klasik kredi skorlamalarında kişinin güvenilirliği belirlenirken kişinin bordrosu, daha önceki kredi/kredi kartı ödemelerindeki düzen, ipotek edebileceği mülkler ve benzeri şeyler dikkate alınır. Bu nedenle bordrolu olarak çalışmayan, hiçbir finansal kuruluşla daha önce etkileşimi olmayan, kredi puanlaması oluşmamış ya da düşük olan kullanıcıların kredi ya da kredi kartı erişimi kısıtlı olmaktadır. Bu kişilere harcamaya bağlı olarak kısa vadeli borç verme olarak görülebilecek kredi olanağı sağlanmaktadır. Hedef müşteri kitlesi arasında farklılıklar olduğu için klasik kredi skorlamaları BNPL’ye başvuran müşterilerin güvenilirlik açısından skorlamasında yetersiz kalmaktadır. Bu nedenle BNPL sisteminin en önemli gereksinimi tüketicilerin güvenilirlik skorlamasının yapılmasıdır. Mevcut durumda BNPL alanında yapılmış çalışmalar kısıtlı olup, BNPL odaklı yeterli bir skorlama sistemi bulunmamaktadır. Bu çalışmada, finansal teknolojilerin önemli bir alanı olan ödeme sistemleri kapsamında, BNPL sistemi üzerine, mevcut durum analizi, fırsatlar ve zorluklar ile skorlama ihtiyacı üzerine sistematik bir yaklaşım sunulmaktadır.
由第四次工业革命引发的金融技术的飞速发展导致了消费者消费行为的改变。与这一变化相适应,"即买即付"(BNPL)系统是在客户需求发生变化后出现的一种新型支付系统技术。BNPL 不是一种现金借贷方式,而是一种购买产品或服务的方式。在电子商务网站或实体店购买喜欢的产品或服务时,必须将付款迅速提供给相应的人。例如,在购买度假套餐时,旅游公司可以为消费者提供不扣除信用卡额度或使用 BNPL 方式信用付款的机会。产品所有者通过银行并根据双边协议提供 BNPL 信贷。而客户则在签约银行的系统中指定公司名称和产品类别,提出 BNPL 贷款申请。同时,相关银行进行可靠性评分,以确定客户是否符合 BNPL 信贷条件,并向得分高的客户发放 BNPL。区别于传统贷款的最重要一点是目标客户群。在传统的信用评分中,在确定一个人的可靠性时,会考虑该人的工资单、以往贷款/信用卡还款的正常性、可抵押的房产等类似情况。因此,没有工资单、以前没有与任何金融机构打过交道、没有信用评分或信用评分较低的用户获得贷款或信用卡的机会有限。向这些人提供的信贷服务可视为基于支出的短期贷款。由于目标客户群之间存在差异,传统的信用评分不足以对申请 BNPL 的客户进行可靠性评分。因此,BNPL 系统最重要的要求是对消费者进行可靠性评分。目前,在 BNPL 领域的研究有限,也没有适当的面向 BNPL 的评分系统。本研究系统地介绍了 BNPL 系统、现状分析、机遇和挑战,以及作为金融技术重要领域的支付系统范围内的评分需求。

Endüstri devriminin tetiklemesiyle hızlı gelişimi, tüketicilerin harcama davranışlarında değişikliklere neden olmuştur. Bu değişime uygun olarak, Şimdi al sonra öde (BNPL) sistemi değişen müşteri ihtiyaçları sonrası ortaya çıkan yeni bir ödeme sistemi teknolojisidir. BNPL nakit borç vermeye değil, ürün ya da hizmet almaya yönelik bir yöntemdir. E-ticaret sitesinde ya da fiziki mağazada beğenilen ürün ya da hizmetin ödemesini uygun kişilere hızlıca sağlamak esastır. Örneğin bir tatil paketi alımında tur şirketleri BNPL yöntemi ile tüketiciye kredi kartı limitinden düşmeden ya da kredi kullandırmadan ödeme yapma olanağı sağlayabilmektedir. Ürün sahibi işletme BNPL kredisini bankalar aracılığı ile ve yapacağı ikili anlaşmalar doğrultusunda sağlamaktadır. Müşteri ise anlaşmalı bankaların sistemlerinden firma ismi ve ürün kategorisi belirterek BNPL kredi talebinde bulunmaktadır. Eş zamanlı olarak ilgili banka da müşterinin BNPL kredisi için uygun olup olmadığını belirlemek için güvenilirlik skorlaması yapmaktadır ve yüksek skoru olan müşteriye BNPL kullandırtmaktadır.

Çocuğun hayatı algılamaya başladığı ilk andan itibaren çevresindeki tüm koşullar gelişim sürecine etki eder. Özellikle çocuğun fizyolojik, psikolojik ve sosyolojik olarak çok yönlü olarak gelişimini destekleyen ve çocukluk döneminde karşılaşılan ilk mekân olan konut, yoğun ve etkin kullanılması nedeni ile ayrı bir öneme sahiptir. Çalışmada, 2-6 yaş dönemindeki çocukların konutu oyun için nasıl kullandığının ortaya koyulması amaçlanmıştır. Bunun için çocukların oyun türleri ile ilgili mekân tercihleri araştırılmıştır. Kapsam çocuğun konutu genel kullanımının yanında, konuttaki mekânlarının oyun türüne ile ilişkili kullanımı ve oyuna bağlı konutun yeterliliği çerçevesinde belirlenmiştir. 2-6 yaş arası çocuk sahibi olan ve Trabzon ilinde yaşayan 94 ebeveyne uygulanan anket ile veri toplanmıştır. SPSS programı ile verilerin genel yüzde dağılımları için frekans analizi ve karşılaştırmalar için ki-kare testi kullanılmıştır. Çocuğun evin her mekânını farklı oyun türleri için kullandığı fakat özel odaya sahip olanların öz gelişimleri için daha kaliteli faaliyetlerde bulunabildikleri, konuttaki oyun tercihini cinsiyet, yaş, özel oda varlığı, oda kullanım süresi ve biçiminin etkilediği, konutun oyun için yeterliliğinde oda sayısı ve gürültü konusunun ön plana çıktığı tespit edilmiştir. Sonuç olarak konuttun tasarımında, kullanıcısı olan çocuğun gereksinimleri ve beklentileri öncelikli belirleyiciler arasında yer almalıdır.
从儿童开始感知生命的第一刻起,他/她周围的所有条件都会影响其成长过程。住房在许多方面支持着儿童的生理、心理和社会学发展,是儿童期最先接触到的地方,其密集和有效的使用具有特殊的重要性。本研究旨在揭示 2-6 岁儿童如何利用住宅进行游戏。为此,调查了儿童对与游戏类型有关的空间的偏好。研究范围是在儿童对住宅的一般使用、与游戏类型相关的住宅空间使用以及住宅是否适合游戏的框架内确定的。对居住在特拉布宗省、子女年龄在 2-6 岁之间的 94 名家长进行了问卷调查,收集了相关 数据。数据的一般百分比分布采用频率分析法,比较采用 SPSS 程序的卡方检验法。性别、年龄、是否有私人房间、使用房间的时间长短和类型都会影响儿童对在家中玩耍的偏好,而房间数量和噪音问题则是影响房屋是否适合玩耍的主要因素。因此,儿童的需求和期望应是住宅设计的主要决定因素。
