The purpose of this study is to investigate the impact of strategy implementation and control as independent variable in enhancing firm’s sustainable competitive advantage through innovation as the dependent variable in the Nigeria’s manufacturing sector. Data were collected through personal questionnaire from 166 manufacturing firms in Nigeria who are members of manufacturing association of Nigeria within North West and North central zones with 70% response rate. The results indicate that there is positive and significant relationship between strategic management elements; implementation and control with sustainable competitive advantage; innovation. According to the result manufacturers in Nigeria fully agree that strategy control is essential when a unique strategy has been implemented so as to successfully enhance sustainable competitive advantage. This study adds Knowledge to the theory and practice of sustainable competitive advantage particularly in Nigeria’s manufacturing firms. Its theoretical and empirical significance adds more insight on the previous empirical studies in the field that is to say it gives guidelines to manufacturers in Nigeria on the impact of strategic management approaches on sustainable competitive advantage. For government and firms, the study provides avenue of enhancing sustainable competitive advantage in Nigeria and Africa as a whole since the phenomena is general.

An Entropy Based Methodology for Valuation of Demand Uncertainty Reduction 基于熵的需求不确定性降低评估方法
IF 0.3 4区 工程技术 Q4 ENGINEERING, MANUFACTURING Pub Date : 2014-04-24 DOI: 10.2139/ssrn.2428870

We propose a distribution-free entropy-based methodology to calculate the expected value of an uncertainty reduction effort and present our results within the context of reducing demand uncertainty. In contrast to existing techniques, the methodology requires neither sampled observations of demand nor a priori assumptions regarding the underlying demand distribution. Rather, leveraging the maximum entropy principle to assign a probability density over all possible demand distributions enables modeling of both one's present state of uncertainty and one's potential future states of uncertainty. We demonstrate that this probability assignment is intuitively satisfying, theoretically justified, and done in a manner that is completely consistent with a decision maker's current information (or lack thereof). Theoretical and numerical results for valuing uncertainty reductions without knowing an underlying demand distribution are explored and contribute to the existing distribution free literature. We leverage these results to answer an often overlooked question in demand management: "Is there value in further reducing my demand uncertainty or do I act on my currently available information?''
我们提出了一种基于无分布熵的方法来计算减少不确定性努力的期望值,并在减少需求不确定性的背景下呈现我们的结果。与现有技术相比,该方法既不需要对需求进行抽样观察,也不需要对潜在需求分布进行先验假设。相反,利用最大熵原理在所有可能的需求分布上分配一个概率密度,可以对当前的不确定状态和潜在的未来不确定状态进行建模。我们证明了这种概率分配在直觉上是令人满意的,理论上是合理的,并且以一种与决策者当前信息(或缺乏信息)完全一致的方式完成。在不知道潜在需求分布的情况下评估不确定性减少的理论和数值结果进行了探索,并为现有的无分布文献做出了贡献。我们利用这些结果来回答需求管理中经常被忽视的问题:“进一步减少我的需求不确定性是否有价值,或者我是否根据我当前可用的信息采取行动?”''

We develop a novel empirical approach to analyze workforce productivity in service systems via timing studies – detailed time-stamped data recording relevant activities performed by the employees processing service requests. Our econometric approach, which is based on models from survival analysis, takes advantage of the detailed information provided by timing study data to capture the time-varying factors that affect productivity, such as the workload level, switching among different tasks and temporary work-relief from breaks during the working shift. We apply our framework in an information technology service delivery system and use the estimated results to evaluate alternative designs of the service system in terms of workforce productivity. Specifically, our methodology can inform decisions regarding workload allocation, routing, prioritization, and working schedule design in a service system.

Abstract In an infinite horizon inventory and sales model, we show that the seller’s unique strategy exhibits increasing prices under general conditions on the revenue function. An increasing discount rate leads to an increase of the time interval between order times, but an increase in batch size has an ambiguous effect.
摘要在无限视界库存与销售模型中,我们证明了在一般条件下,卖方的唯一策略在收益函数上表现为价格递增。贴现率的增加导致订单时间间隔的增加,但批量大小的增加有一个模糊的影响。

We model a supply chain scenario in which the genuine manufacturer is uncertain whether a retailer sells counterfeits alongside authentic products. We evaluate the optimal strategies for players under wholesale price contracts and two-part tariff contracts and analyse the impact of the uncertainty of retailer counterfeiting on the manufacturer’s pricing and expected profits. Furthermore, we investigate whether the two-part tariff is more effective compared with the wholesale price contract.
我们模拟了一个供应链场景,其中正品制造商不确定零售商是否在销售正品的同时销售假冒产品。我们评估了批发价格合同和两部分关税合同下参与者的最优策略,并分析了零售商假冒的不确定性对制造商定价和预期利润的影响。此外,我们研究了两部分关税是否比批发价格合同更有效。

The Agency Model for Digital Goods 数字商品的代理模式
IF 0.3 4区 工程技术 Q4 ENGINEERING, MANUFACTURING Pub Date : 2013-12-11 DOI: 10.2139/ssrn.2297484

While digital goods industries such as entertainment, software, and publishing are growing at a rapid pace, traditional supply chain contract models have failed to evolve with the new digital economy. To illustrate, the agency model utilized by the e-book publishing industry has recently received much negative attention brought by the U.S. Department of Justice's lawsuit against Apple, Inc. The emerging agency model in the e-book industry works as follows: the publisher sets the price of the digital goods and the retailers who serve as agents retain a percentage of the revenue associated with a consumer purchase. The regulators claim that the agency model is hurting this industry as well as the consumer's welfare because e-book prices have increased after the introduction of the agency model. We investigate the strategic impact of the agency model by examining a digital goods supply chain with one supplier and two competing retailers. In comparison to the benchmark wholesale model, we find that the agency model can coordinate the competing retailers by dividing the coordinated profits into a prenegotiated revenue sharing proportion. Further, we also identify the Pareto improving region whereby both the supplier and the retailers prefer the agency model to the wholesale model. Our main qualitative insight regarding the agency model still holds even when we consider the presence of the printed books in the marketplace. Thus, contrary to current press presaging the negative impact of the agency model on the e-books industry, we find the agency model to be superior to the traditional wholesale contracts for publishers, retailers and consumers in this digital goods industry.
虽然娱乐、软件和出版等数字商品行业正在快速发展,但传统的供应链合同模式已经无法跟上新的数字经济的发展。为了说明这一点,电子图书出版业所采用的代理模式最近受到了美国司法部起诉苹果公司的负面关注。电子书行业新兴的代理模式是这样运作的:出版商设定数字产品的价格,而作为代理的零售商从消费者购买的图书中获得一定比例的收入。监管机构声称,代理模式不仅损害了消费者的福利,也损害了整个行业,因为引入代理模式后,电子书的价格上涨了。我们通过一个供应商和两个竞争零售商组成的数字商品供应链来研究代理模型的战略影响。与基准批发模型相比,我们发现代理模型可以通过将协调的利润分成预先协商好的收益分成比例来协调竞争的零售商。此外,我们还确定了帕累托改进区域,其中供应商和零售商都更倾向于代理模式而不是批发模式。我们关于代理模式的主要定性见解仍然成立,即使我们考虑了市场上印刷书籍的存在。因此,与目前媒体预测代理模式对电子书行业的负面影响相反,我们发现代理模式在这个数字商品行业中对出版商、零售商和消费者来说都优于传统的批发合同。

Given uncertain popularity of new products by location, fast fashion retailer Zara faces a trade-off. Large initial shipments to stores reduce lost sales in the critical first days of the product life cycle, but maintaining stock at the warehouse allows restocking flexibility once initial sales are observed. In collaboration with Zara, we develop and test a decision support system featuring a data-driven model of forecast updating and a dynamic optimization formulation for allocating limited stock by location over time. A controlled field experiment run worldwide with 34 articles during the 2012 season showed an increase in total average season sales by approximately 2% and a reduction in the number of unsold units at the end of the regular selling season by approximately 4%.
由于新产品在不同地区的受欢迎程度不确定,快时尚零售商Zara面临着权衡。在产品生命周期的关键最初几天,向商店的大量初始货物减少了销售损失,但在仓库中保持库存可以在观察到初始销售后灵活地补充库存。在与Zara的合作中,我们开发并测试了一个决策支持系统,该系统具有数据驱动的预测更新模型和动态优化公式,可以随着时间的推移分配有限的库存。2012年销售季,在全球范围内对34种产品进行了实地对照试验,结果显示,平均销售季总销量增长了约2%,常规销售季结束时未售出的产品数量减少了约4%。

Managing Supply Risk for Vertically Differentiated Co-Products 垂直差异化产品的供应风险管理

The manufacturing complexity of many high-tech products results in a substantial variation in the quality of the units produced. Post manufacturing, the units are classified into vertically differentiated products. These products are typically obtained in uncontrollable fractions, leading to mismatches between their demand and supply. We focus on product stock-outs due to the supply-demand mismatches. Existing literature suggests that when faced with product stock-outs, firms should satisfy all unmet demand of a low-end product by downgrading excess units of a high-end product (downward substitution). However, this policy may be sub-optimal if it is likely that low-end customers will substitute with a higher quality product and pay the higher price (upward substitution). In this paper, we investigate whether and how much downward substitution firms should perform. We also investigate whether and how much low-end inventory firms should withhold to strategically divert some low-end demand to the high-end product. We first establish the existence of regions of co-production technology and willingness of customers to substitute upwards where firms adopt different substitution/withholding strategies. Then, we develop a managerial framework to determine the optimal selling strategy during the life cycle of technology products as profit margins shrink, manufacturing technology improves, and more capacity becomes available. Consistent trends exist for exogenous and endogenous prices.
许多高科技产品制造的复杂性导致生产出来的产品质量有很大差异。制造后,将单元划分为垂直差异化产品。这些产品通常以不可控的馏分获得,导致它们的需求和供应不匹配。我们关注由于供需不匹配导致的产品缺货。现有文献表明,当面临产品缺货时,企业应该通过降低高端产品的过剩单位(向下替代)来满足所有低端产品的未满足需求。然而,如果低端客户可能会用更高质量的产品替代,并支付更高的价格(向上替代),则该策略可能是次优的。本文主要研究企业是否应该进行向下替代,以及向下替代的程度。我们还研究了低端库存企业是否应该保留以及保留多少库存以战略性地将一些低端需求转移到高端产品。首先,在企业采用不同替代/代扣策略的情况下,我们建立了合作生产技术区域和消费者向上替代意愿的存在性。然后,我们开发了一个管理框架,以确定在技术产品的生命周期内,随着利润率的缩小,制造技术的改进,更多的产能变得可用的最优销售策略。外生和内生价格的趋势是一致的。

Cartel Formation through Strategic Information Leakage in a Distribution Channel 分销渠道中战略信息泄露的卡特尔形成
IF 0.3 4区 工程技术 Q4 ENGINEERING, MANUFACTURING Pub Date : 2013-07-11 DOI: 10.2139/ssrn.2292410

This paper studies the ability of competing retailers to form a cartel by sharing information with their mutual manufacturer. In a market characterized by demand uncertainty, colluding retailers wish to share information about the potential market demand to coordinate on the optimal collusive retail price. However, in light of potential exposure to antitrust investigations and possible sanctions, the retailers search for mechanisms to exchange information while avoiding the risks of scrutiny by the antitrust authorities. This paper examines such a mechanism: each retailer shares his private information with the mutual manufacturer; the wholesale price set by the latter is thereafter used by the retailers to infer the market condition and coordinate on the cartel’s price. Although a cartel at the retail level limits the manufacturer’s sold quantity, under certain conditions the manufacturer is better off accepting the retailers’ private information, thereby assisting the cartel formation. Moreover, vertical information sharing between the retailers and their mutual manufacturer can result in lower consumer surplus than that would have occurred had the retailers been permitted to collude directly.
本文研究了相互竞争的零售商通过与其共同的制造商共享信息而形成卡特尔的能力。在需求不确定的市场中,串通零售商希望共享潜在市场需求信息,以协调最优串通零售价格。然而,考虑到可能面临的反垄断调查和可能的制裁,零售商寻求在避免反垄断当局审查风险的同时交换信息的机制。本文研究了这样一种机制:每个零售商与相互制造商共享自己的私人信息;零售商利用卡特尔制定的批发价格来推断市场状况,并就卡特尔的价格进行协调。尽管零售层面的卡特尔限制了制造商的销售数量,但在一定条件下,制造商最好接受零售商的私人信息,从而有助于卡特尔的形成。此外,与允许零售商直接串谋相比,零售商与其共同制造商之间的垂直信息共享可能导致更低的消费者剩余。

Moreover, vertical information sharing between the retailers and their mutual manufacturer can result in lower consumer surplus than that would have occurred had the retailers been permitted to collude directly.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"117 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2013-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81018971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article studies the impact of modular assembly on supply chain efficiency. In the modular assembly approach, a manufacturer acquires pre-assembled modules from its suppliers, rather than the individual components, as in the traditional assembly approach. We analyze the competitive behavior of a two-stage modular assembly system consisting of a manufacturer, and a supplier who pre-assembles two components into a module. The firms can choose their own inventory policies and we show the existence of Nash equilibrium in the inventory game. Moving from the traditional to the modular approach has a twofold effect on the supply chain. First, we investigate the effect of centralizing the component suppliers. It can be shown that when there is no production time shift, the module supplier always holds more component inventories than suppliers do in the traditional approach, which yields a lower cost for the manufacturer. However, the suppliers, and therefore the supply chain may incur a higher cost in the modular approach. Second, we study the effect of a shift in production time from the manufacturing stage to the supplier stage. From numerical studies, it has been found that such a lead time shift always benefits a centralized supply chain, but not necessarily so for a decentralized system. Combining the two effects, we find that the modular approach generally reduces the cost to the manufacturer and the supply chain, which explains the prevalence of modular assembly from the perspective of inventory management. These results also provide some insight into how firms can improve supply chain efficiency by choosing the right decision structure and lead time configuration.
本文研究了模块化装配对供应链效率的影响。在模块化组装方法中,制造商从供应商那里获得预组装的模块,而不是像传统的组装方法那样获得单个组件。本文分析了一个两阶段模块化装配系统的竞争行为,该系统由一个制造商和一个预先将两个组件组装成一个模块的供应商组成。企业可以选择自己的库存策略,并证明了在库存博弈中存在纳什均衡。从传统到模块化的转变对供应链有双重影响。首先,我们考察了零部件供应商集中化的影响。结果表明,在不存在生产时间转移的情况下,组件供应商的组件库存总是比传统方法下的供应商多,这使得制造商的成本更低。然而,在模块化方法中,供应商以及供应链可能会产生更高的成本。其次,我们研究了生产时间从制造阶段转移到供应商阶段的影响。从数值研究中发现,这种交货期变化总是有利于集中式供应链,但对于分散系统则不一定如此。结合这两种影响,我们发现模块化方式通常降低了制造商和供应链的成本,这从库存管理的角度解释了模块化装配的流行。这些结果也为企业如何通过选择正确的决策结构和提前期配置来提高供应链效率提供了一些见解。
