Risk pooling approach in multi-product multi-period inventory control model under uncertainty 不确定条件下多产品多周期库存控制模型中的风险分担方法
Peeyush Vats, G. Soni, A. Rathore, Jayant K. Purohit
Risk pooling is an approach which is majorly supportive for maintaining the safety stock up to a minimum level under uncertain conditions. This pooling method decreases the inventory carrying costs, overhead costs and other costs involved in maintain the facility, Therefore this approach can be suitably implemented in an inventory control model. The major concentration of this study is to develop a multi-product multi-period inventory control model in two stage supply chain network which mainly consists of distributors and retailers. Inventory carrying costs, transportation costs, facility operating cost, ordering costs and facility cost are incorporated for the formulation of inventory control model in objective function under various constraints. A non-linear programming has been originated to solve the proposed mathematical model. The results and the performance parameters can be assessed under various uncertain levels.
风险分担是在不确定条件下将安全库存维持在最低水平的一种主要支持方法。该方法降低了库存持有成本、间接成本和其他维护设备的成本,因此可以适用于库存控制模型。本研究的重点是建立以分销商和零售商为主体的两阶段供应链网络中多产品多周期的库存控制模型。将库存持有成本、运输成本、设备运行成本、订货成本和设备成本纳入目标函数,在各种约束条件下建立库存控制模型。提出了一种非线性规划方法来求解所提出的数学模型。结果和性能参数可以在各种不确定水平下进行评估。

Factors Affecting the Sustainability of SME Industries: A Case Study in the Southern Province of Sri Lanka 影响中小企业可持续发展的因素:以斯里兰卡南部省为例
J. Haresankar, U. Galappaththi, R. L. Perera
The Small and Medium Enterprises’ (SMEs) growth in Sri Lanka is negatively affected by several factors such as lack of financial management, education facilities for the SMEs, less technological support, social issues, obstructive legal policies, limited financial support schemes, and problematic ethical factors. The current study is focusing on the Southern Province of Sri Lanka since it was noticed that the relative dominance of these factors is different compared to the other Provinces in Sri Lanka. This project focuses on evaluating fundamental factors required for developing a strong foundation for emerging sustainable SMEs and comparison of these factors statistically, and qualitatively in SMEs of the Southern Province of Sri Lanka. The coordination of the research was comprised with literature review, questionnaires, interviews and inspection analysis to provide information for solutions. The studies in legal policies, balance maintenance on asymmetrical knowledge, political stability, capital strength, organization morale, technical background were analyzed on countries such as USA, India, and China, and also on well established Western and Central Provinces in Sri Lanka, which eventually provided us with a good contrast. These data were used to investigate the shortcomings of SMEs in the Southern Province and showed an overall result that 53% of SMEs have failed due to above factors. The study can also be expanded to a wider picture to answer factors affecting the sustainability of SMEs in Sri Lanka compared to other nations. The research will provide valuable insights to support the growth of SMEs in the Southern Province of Sri Lanka.
斯里兰卡的中小企业(SMEs)的增长受到几个因素的负面影响,如缺乏财务管理,中小企业的教育设施,较少的技术支持,社会问题,阻碍法律政策,有限的金融支持计划和有问题的道德因素。目前的研究主要集中在斯里兰卡南部省份,因为人们注意到这些因素的相对主导地位与斯里兰卡其他省份不同。该项目侧重于评估为新兴的可持续中小企业奠定坚实基础所需的基本因素,并在斯里兰卡南部省的中小企业中对这些因素进行统计和定性比较。研究的协调包括文献综述、问卷调查、访谈和检验分析,以提供解决方案的信息。在法律政策、不对称知识的平衡维护、政治稳定性、资本实力、组织士气、技术背景等方面的研究,我们分析了美国、印度、中国等国家,以及斯里兰卡历史悠久的西部和中部省份,最终为我们提供了一个很好的对比。利用这些数据对南方省中小企业的不足进行了调查,结果显示,53%的中小企业由于上述因素而失败。该研究还可以扩展到更广泛的情况,以回答影响斯里兰卡中小企业与其他国家相比可持续性的因素。该研究将为支持斯里兰卡南部省中小企业的发展提供有价值的见解。

Remanufacture for Sustainability: A review of the barriers and the solutions to promote remanufacturing 面向可持续性的再制造:促进再制造的障碍与对策综述
Hasith Gunasekara, J. Gamage, H. Punchihewa
Remanufacturing is the only end-of-life process where used products are brought back to the Original Equipment Manufacturers’ (OEM) performance specification from the customers’ perspective. At the same time, it offers a warranty equal or better to that of corresponding new products. During this process, products are returned to their original state with minimum waste of material and energy. Moreover, the benefits of remanufacturing are not only limited to ecological aspects but also it provides a win-win situation for both the customer and the remanufacturer. Nevertheless, remanufacturing systems are inherited with more complex production planning and control activities due to the difficulties and uncertainties in product take-back compared to traditional manufacturing. The purpose of this review is to identify the main barriers of remanufacturing. Identified barriers are categorised according to the triple helix of the innovation model. The paper also reviews the solutions provided in the rest of the world in addressing the barriers of remanufacturing.
从客户的角度来看,再制造是唯一一个将使用过的产品带回原始设备制造商(OEM)性能规范的生命周期结束过程。同时提供与相应新产品同等或更好的保修期。在这个过程中,产品恢复到原来的状态,最大限度地减少材料和能源的浪费。此外,再制造的好处不仅仅局限于生态方面,它还为客户和再制造商提供了双赢的局面。然而,由于产品回收的困难和不确定性,与传统制造相比,再制造系统继承了更复杂的生产计划和控制活动。本综述的目的是找出再制造的主要障碍。根据创新模型的三螺旋结构对已识别的障碍进行分类。本文还回顾了世界其他国家在解决再制造障碍方面提供的解决方案。

Taxonomy for Classifying Products on the Customization Spectrum 基于定制谱的产品分类方法
Oscar Rincón-Guevara, Jorge A. Samayoa, A. Deshmukh
A recent trend has been to compete in the marketplace by allowing customers to personalize products to best meet their needs and taste. Enhanced customization increases variability and complexity in the manufacturing systems and supply chains supporting the manufacture and delivery of these products. The range or amount of customization practical for a product depends on several factors, such as its architecture, materials, manufacturing processes, supplier capabilities, customer interaction with design architecture, etc. Products can be placed on a spectrum of customization, ranging from Mass-Production (minimal customization), to Mass-Customization (standard design with some degree of customization), to Mass-Individualization (customer involved in the design process to co-create the product). A key question for the organization is to determine which of these levels of customization is best suited for their product, given the customer requirements, the product architecture, and the necessary manufacturing capabilities.This paper reviews the extant literature on personalization and customization. We propose a taxonomy to identify salient characteristics of different customization paradigms. We use this taxonomy to identify what products belong to each customization paradigm. Additionally, we summarize different taxonomies considering their application context, pros, and cons of each. Finally, we apply our taxonomy to three example products, where we consider customer engagement point, product architecture, assembly configuration, and technology flexibility.
最近的一个趋势是在市场上竞争,允许客户个性化的产品,以最好地满足他们的需求和品味。增强的定制增加了制造系统和支持这些产品的制造和交付的供应链中的可变性和复杂性。一个产品的定制范围或数量取决于几个因素,比如它的架构、材料、制造过程、供应商能力、客户与设计架构的交互等等。产品可以被放置在定制的范围内,从大规模生产(最小定制)到大规模定制(带有一定程度定制的标准设计),再到大规模个性化(客户参与设计过程共同创造产品)。组织面临的一个关键问题是,在给定客户需求、产品架构和必要的制造能力的情况下,确定哪一种定制级别最适合他们的产品。本文对现有的关于个性化和定制的文献进行了综述。我们提出了一种分类法来识别不同定制范例的显著特征。我们使用这个分类法来确定哪些产品属于每个定制范例。此外,我们还总结了不同的分类法,考虑了它们的应用程序上下文、优缺点。最后,我们将分类法应用于三个示例产品,其中我们考虑客户参与点、产品体系结构、装配配置和技术灵活性。

Modelling sustainable supply networks with adaptive agents 基于自适应代理的可持续供应网络建模
Subodha Dharmapriya, Senevi B. Kiridena, N. Shukla
This paper proposes a multi-agent modelling approach that supports supply network configuration decisions towards sustaining operations excellence in terms of economic, business continuity and environmental performance. Two types of agents are employed, namely, physical agents to represent supply entities and auxiliary agents to deal with supply network configuration decisions. While using the evolutionary algorithm, Non-dominated Sorting Genetic Algorithm-II to optimize both cost and lead time at the supply network level, agents are modelled with an architecture which consists of decision-making, learning and communication modules. The physical agents make decisions considering varying situations to suit specific product-market profiles thereby generating alternative supply network configurations. These supply network configurations are then evaluated against a set of performance metrics, including the energy consumption of the supply chain processes concerned and the transportation distances between supply entities. Simulation results generated through the application of this approach to a refrigerator production network show that the selected supply network configurations are capable of meeting intended sustainable goals while catering to the respective product-market profiles.
本文提出了一种多代理建模方法,该方法支持供应网络配置决策,以在经济、业务连续性和环境绩效方面保持卓越的运营。采用了两种类型的代理,即代表供应实体的物理代理和处理供应网络配置决策的辅助代理。采用进化算法非支配排序遗传算法(non - dominant Sorting Genetic algorithm - ii)在供应网络层面对成本和交货期进行优化,构建了一个由决策、学习和沟通模块组成的体系结构。物理代理根据不同的情况做出决定,以适应特定的产品市场概况,从而产生可替代的供应网络配置。然后根据一组性能指标对这些供应网络配置进行评估,包括相关供应链流程的能耗和供应实体之间的运输距离。通过将该方法应用于冰箱生产网络产生的仿真结果表明,所选的供应网络配置能够满足预期的可持续目标,同时满足各自的产品市场概况。

Improving the Reliability of Warehouse Operations in the 3PL Industry: An Australian 3PL Case Study 提高仓库操作的可靠性在第三方物流行业:澳大利亚第三方物流案例研究
T. K. D. Ho, J. Daniel, Simon Peter Nadeem, J. Garza‐Reyes, Vikas Kumar
Warehouses play an important value-adding role to provide a competitive edge, support business growth and efficiency throughout their supply chains. This paper explores warehouse operations (i.e. receiving, put away, picking, packing and shipping) and a series of challenges faced in managing warehouse operations in general and the 3PL industry in particular. Especially, the paper analyses the warehouse and logistics operations of an Australian 3PL company. By utilizing a mixed method approach both qualitative and quantitative data was gathered through in-depth interviews, direct observations and warehouse operations records. The collected data were then analyzed using thematic analysis. The data was screened and coded to further develop major themes to identify the problematic areas. This analysis helped to identify issues in operations related to the receiving process, missing, picking and locating items as well as human errors. While multiple approaches could be utilized to improve the operations, there yet remained a major challenge to manage operations within the planned budgetary limits. This research, therefore, provides some solutions/recommendations to improve the case company’s warehouse operations through staff empowerment, management process improvement, order dispatch and return process improvement, improvement in record keeping, and recruiting more personnel. These recommendations ensure company’s efficiency while balancing its challenges both in operations and budgetary constraints. This study thus provides an evidence to improve the reliability of warehouse operations through systematic process improvement.
仓库在提供竞争优势、支持整个供应链的业务增长和效率方面发挥着重要的增值作用。本文探讨了仓库操作(即接收、存放、拣选、包装和运输)以及管理仓库操作所面临的一系列挑战,特别是第三方物流行业。本文特别分析了澳大利亚一家第三方物流公司的仓储和物流运作。通过采用混合方法,通过深入访谈、直接观察和仓库操作记录收集了定性和定量数据。然后使用专题分析对收集到的数据进行分析。对数据进行了筛选和编码,以进一步制定主要主题,以确定问题领域。这种分析有助于识别与接收过程、丢失、挑选和定位物品以及人为错误相关的操作问题。虽然可以采用多种方法来改进业务,但在计划的预算限制范围内管理业务仍然是一个重大挑战。因此,本研究从员工授权、管理流程改进、订单调度和退货流程改进、记录保存改进、招聘更多人员等方面为案例公司的仓储运营提供了一些改进的解决方案/建议。这些建议确保公司的效率,同时平衡其在运营和预算限制方面的挑战。本研究为通过系统的流程改进来提高仓储作业的可靠性提供了依据。

The challenges of GSCM implementation in the UK manufacturing SMEs GSCM在英国制造业中小企业实施的挑战
Vikas Kumar, Shahruzzaman Sabri, J. Garza‐Reyes, Simon Peter Nadeem, A. Kumari, Supalak Akkaranggoon
The importance of green supply chain management has long attracted the interest of both researchers and practitioners in the industry. As environmental concerns are becoming one of the major issues discussed in the 21st century, countries with manufacturing as its principal economy contributor are always on the lookout for innovations and new approaches to balance both environmental considerations and profit making. The UK, being one of the top manufacturing countries in the world already considered green initiatives among their manufacturers. According to reports from the industry, large and international manufacturing companies from the UK have successfully implemented some green initiatives with significant improvements across the supply chain. However, the adoption of green initiatives is mainly focused on large companies rather the real backbone of the UK manufacturing industry, which is the small and medium-sized enterprises (SMEs). This paper therefore sets out to determine the implementation level of green supply chain among the SMEs. The paper adopts a mixed methods based approach and findings are based on 57 survey responses and 5 semi-structured interviews from UK manufacturing SMEs. The findings show that the level of GSCM implementation among the UK manufacturing SMEs is low compared to large organisations. Cost of implementing GSCM practices emerged as a key challenge faced by the UK manufacturing SMEs which was followed by the lack of knowledge within the organisation. This study thus adds to the limited literature on the manufacturing SMEs and provides evidence from the UK manufacturing sector on the adoption of GSCM practices.
长期以来,绿色供应链管理的重要性吸引了业内研究者和实践者的兴趣。随着环境问题成为21世纪讨论的主要问题之一,以制造业为主要经济贡献者的国家总是在寻找创新和新的方法来平衡环境考虑和盈利。英国作为世界上最大的制造业国家之一,已经在其制造商中考虑了绿色倡议。根据该行业的报告,来自英国的大型和国际制造公司已经成功地实施了一些绿色倡议,并在整个供应链中取得了重大进展。然而,绿色倡议的采用主要集中在大公司,而不是英国制造业的真正支柱,即中小型企业(SMEs)。因此,本文着手确定绿色供应链在中小企业中的实施水平。本文采用混合方法为基础的方法和研究结果是基于57个调查回应和5个半结构化访谈从英国制造业中小企业。研究结果表明,与大型组织相比,英国制造业中小企业实施GSCM的水平较低。实施GSCM实践的成本成为英国制造业中小企业面临的一个关键挑战,随之而来的是组织内部缺乏知识。因此,本研究增加了对制造业中小企业的有限文献,并提供了英国制造业采用GSCM实践的证据。

A Conceptual Framework to assess the Applicability of Agile Manufacturing Techniques 评估敏捷制造技术适用性的概念框架
Lvk Withanagamage, R. Ratnayake, EJ Wattegama
Agile manufacturing has emerged as an extension to lean manufacturing to increase the quickness, flexibility, responsiveness, and competence of the manufacturing facilities. Agility drivers can be used to investigate the necessity of being agile in the business environment. When agile manufacturing techniques are implemented, existing capabilities of the industry should be identified. Afterwards the missing capabilities can be identified and need to be acquired. The objective of the present study is to develop a conceptual framework to assess whether the industry is required to be agile and capable enough to implement agile manufacturing techniques. In achieving it, a content analysis was performed using available literature and industry experts were interviewed. The propositions that have been introduced by the present study could be tested and validated by future researchers to draw theoretical and managerial implications of the proposed conceptual framework.
敏捷制造作为精益制造的延伸而出现,以提高制造设备的快速性、灵活性、响应性和能力。敏捷驱动程序可用于调查在业务环境中保持敏捷的必要性。当实现敏捷制造技术时,应该确定行业的现有能力。之后,可以识别缺失的功能,并需要获得这些功能。本研究的目的是开发一个概念框架,以评估行业是否需要敏捷和有足够的能力来实施敏捷制造技术。为了实现这一目标,我们利用现有文献进行了内容分析,并采访了行业专家。本研究提出的命题可以由未来的研究人员进行测试和验证,以得出所提出的概念框架的理论和管理意义。
