Problem – Companies and supply chains, such as those in the grocery industry, continuously face stricter requirements in the form of customer satisfaction, quality, profit margins, as well as information sharing in order to stay competitive. One specific technology that may be used in dealing with increasing competitive demands is the radio frequency identification (RFID) technology. A wide body of research recognizes the positive impacts from RFID, yet even so, doubts and uncertainty have been present among different supply chain members in industries striving to put the RFID technology to use. Nevertheless, many actors in the Norwegian grocery industry are replacing traditional wood pallets with plastic pallets, and these pallets are integrated with RFID tags. Purpose – The purpose of this thesis is to investigate how plastic pallets with integrated RFID tags can contribute to improve supply chain efficiency in the grocery industry. Also, the managerial perception on the pallets and their accompanying technology will be compared to the existing literature, to identify if the managerial opinion supports the literature, and if not, where the gaps exist. Method – The thesis combines an exploratory and an explanatory qualitative study of the managerial perception of RFID pallets in the Norwegian grocery industry, and investigates whether the perception supports the literature. The empirical material is gathered through telephone interviews with logistics and warehouse managers in the various companies. Conclusions – Physical implications: The managerial perceptions’ support towards the addressed implications of the reviewed literature is mixed. RFID pallets improve automatic operation processes through reduction in downtime and eases physical handling of pallets. Additionally, sorting of pallets becomes less labor demanding. Regarding holding of goods, the managerial perceptions do not seem to view RFID pallets as an important factor for efficiency improvement. Information related/RFID aspects’ implications: The managerial perceptions in these concerns were based on plans and thoughts, since the technology had not been put to use. There is a difference in producers’ and wholesalers’ perception of whether efficiency in receiving of goods can be improved through utilizing RFID pallets. Concerning dispatching of shipments, the managerial perceptions support the literature in that information-related activities can be automated, and thus improve efficiency and reduce risk of human errors. In regards to information sharing, the managerial perception supports the literature, but highlights that the information’s nature determines whether sharing is considered. Further research could include the retail store level to get a more complete supply chain picture, and also apply the research methods to a larger area in order to investigate the transferability to other industries and countries.

Linnaeus University, School of Management and Economics, 5FE00E, Spring 2010 Author: Hana Hulthén Tutor: Helena Forslund Title: Information integration between retailers and manufacturers in Swedish food retail supply chains; The manufacturers’ perspective.  Background: According to study conducted by Brege in 2007, in Swedish food retail supply chains there is lack of external integration between retailers/wholesalers and manufacturers. This fact indicates that there are gaps in information integration between them which have consequences mainly for the manufacturers. Purpose: The purpose of this study is to describe gaps, from the manufacturers´ perspective, in the information integration between Swedish retailers/wholesalers and manufacturers, and analyze what are the consequences of these gaps for manufacturers as well as propose how these gaps can be alleviated. Method: Multiple - case study as research method has been applied. Specifically, three case companies, Swedish meat manufacturers, have been selected. Three one-hour long focused interviews combined with open-ended interviews have been conducted with two sales managers and one sales representative. The empirical evidence has been analyzed by using cross-case analysis method and pattern-matching method.   Results, conclusion: Firstly, Swedish meat manufacturers do not have access to real-time demand or POS data on store level. Instead, they receive orders from retailers based on updated demand forecast. As manufacturers do not have perfect demand information it leads to information asymmetry between retailers and manufacturers. As a consequence of inaccurate demand signal processing a Bullwhip effect can occur. Implementation of integrated information systems using EDI for exchange of POS data could solve the gap. However, small-scaled manufacturers have neither enough resources nor incentives to invest in an expensive business-to-business system. Furthermore, manufacturers with restricted production flexibility cannot utilize provided information on very detailed level; such as POS data. Thus, in these cases implementation of integrated information systems seems not to be reasonable. Secondly, it has been found that information integration between retailers and manufacturers has been significantly improved the last three or four years. The Swedish retailers are willing to provide information to manufacturers. Future Work: The result of this thesis is based only on findings from meat manufacturers. Other sectors could be also included as well as opinion of retailers and wholesalers to identify common problems related to information integration in Swedish food retail supply chains.

Med större krav på effektivisering och pressade kostnader har VMI på senare tid blivit en allt mer tillämpad metod för att samordna aktiviteterna i försörjningskedjan. Mycket forskning har gjorts kring ämnet VMI och dess fördelar. Däremot har inte mycket skrivits om initiativtagande och hur dessa samarbeten uppstår. Syftet med uppsatsen är att undersöka företag som tillämpar VMI. Detta för att ta reda på vem, kunden eller leverantören, som tar initiativet till samarbetet och varför. Utifrån detta vill vi även identifiera konsekvenser kopplade till vem som tog initiativet. Genom vår undersökning har vi kommit fram till att kunden så väl som leverantören kan vara initiativtagare. Detta för att det finns vinster att göras för båda parter. Vi har kunnat identifiera att den främsta anledningen till initiativtagande är de fördelar som ses för det egna företaget. En annan bidragande faktor är även att företagen vill skapa långsiktiga relationer. Vi har genom vår studie inte kunnat identifiera några konsekvenser i samarbetet som är direkt kopplade till vem som tar initiativet. Däremot har vi sett indikationer på att den part som tar initiativet är den som ofta bäst lyckas påverka villkoren för samarbetet.

Algorithmic Framework for Improving Heuristics in Stochastic, Stage-Wise Optimization Problems Jaein Choi 172 Pages Directed by Dr. Jay H. Lee and Dr. Matthew J. Realff The goal of this thesis is the development of a computationally tractable solution method for stochastic, stage-wise optimization problems. In order to achieve the goal, we have developed a novel algorithmic framework based on Dynamic Programming (DP) for improving heuristics. The propose method represents a systematic way to take a family of solutions and patch them together as an improved solution. However, patching is accomplished in state space, rather than in solution space. Since the proposed approach utilizes simulation with heuristics to circumvent the curse of dimensionality of the DP, it is named as Dynamic Programming in Heuristically Restricted State Space. The proposed algorithmic framework is applied to stochastic Resource Constrained Project Scheduling problems, a real-world optimization problem with a high dimensional state space and significant uncertainty equivalent to billions of scenarios. The real-time decision making policy obtained by the proposed approach outperforms the best heuristic applied in simulation stage to form the policy. The proposed approach is extended with the idea of Q-Learning technique, which enables us to build empirical state transition rules through simulation, for stochastic optimization problems with complicated state transition rules. Furthermore, the proposed framework is applied to a stochastic supply chain management problem, which has high dimensional action space as well as high dimensional state space, with a novel concept of implicit sub-action space that efficiently restricts action space for each state in the restricted state space. The resulting real-time policy responds to the time varying demand for products by stitching together decisions made by the heuristics and improves overall performance of the supply chain. The proposed approach can be applied to any problem formulated as a stochastic DP, provided that there are reasonable heuristics available for simulation.

Product proliferation is a common challenge for firms providing customized products. To cope with this challenge, firms usually incorporate strategies such as component commonality, postponement, and/or delayed differentiation in their supply chains. In this dissertation, we study the effectiveness of these strategies. First, we evaluate the inventory costs for various percentages of common component substitution. Second, we analyze the performance of two postponement strategies and their relationship with product proliferation. Third, we study the cost and benefits of implementing delayed differentiation in a make-to-order environment and provide insights for managers choosing where along the supply chain they should differentiate their products.

To date, closed form optimal solutions for stocking levels in arborescent multiechelon inventory systems have not been obtained. These problems exhibit the joint difficulties of requiring an allocation policy as well as a stocking policy, and the multidimensional nature of their state space makes dynamic programming formulations impractical. In this dissertation, we introduce procedures that approximate multiechelon networks with sets of single installation problems. We first use this technique to solve for base-stock levels in a distribution network with asymmetric retailers. Second, we use this technique to analyze delayed differentiation production processes and provide guidance as to when the strategy is most warranted. Third, we modify the technique to account for inventory that exhibits perishability and solve for stocking policies for distribution systems when the inventory has a fixed shelf life.

Since the Canadian nuclear reactor ¡§NRU¡¨ was shut down on 14th May, 2009, the global Moly shortage has occurred for a year. The crisis was not only an impact for the patients of the hospitals in Taiwan, but also decreased the sales and margin profit of the nuclear medicine distributors. The S company, a leading and monopolistical distributor in Taiwan, was no longer reliable for its customers because of the nuclear medicine shortage. Actually it looks like the advantage of the S company is lost and the reputation is damaged. This research is trying to figure out how a nuclear medicine distributor like the S company can pursue some effective supply chain strategies to turn around and keep the growth of profit. AHP is the study method for this research. But at first we¡¦ll plan some strategies and tactics for the nuclear medicine distributors (especial the S company), according to Potters¡¦ competition theory and the resource based view of the firm. And then develop the two levels structure for the AHP study in this research. The factors of upper level are 4 strategies, like ¡§Research & Development Strategy¡¨ etc. The factors of lower level are 18 tactics or plans just like ¡§Try to acquire new technology from the advanced radiopharmaceutical institutes¡¨ etc. The AHP will be performed by surveys of experts¡¦ opinions, including both qualitative and quantitative surveys. Five different groups of experts were sampling and chosen for the surveys. By the AHP, the two most weights of the tactics are determined. They are ¡§Integrate individual (country) procurement into multinational procurement for reducing cost¡¨ and ¡§Actively globalized procurement, and monopolistically securing the sources¡¨. Besides, we can discover more valuable opinions from the qualitative analysis of the expert¡¦s surveys. So the results of this research, the effective and advanced strategies and tactics, are the first securing more reliable sources of the nuclear medicine and the second improving globalized procurement. And then try to enhance marketing and strengthen customer relationship. These will be expected to be helpful on both distributors¡¦ profit and customers¡¦ satisfaction.

­^¤åºK­n The purpose of this research is to study the evaluation and management system of multinational suppliers, which includes the followings. 1. To summary and compile various study and theory of supplier management and evaluation, and to analysis the infrastructure and characteristic of each method. 2. Based on previous study and cases reviewing, this study aims to study how a multinational company well management the suppliers from different countries, and how to elevate the company¡¦s benefit by building up the multinational supplier evaluation and management system. The result of the study of case company shows good effects after the establishment of SEAP system. The analysis on purchasing risk, technical ability, supplier behavior management ability, direction management ability, informatics technology management and performance on strategy, economic and technique, showed better result after the establishment and adoption of SEAP system. The study also indicated that the benefit and advantage derived from the establishment of well supplier evaluation and management system. All multinational companies should not ignore its importance. In addition, this study also suggests several important though in the management of multinational suppliers, which include: a company should well established the relationship with the suppliers with an all-directional though and well, to view the suppliers the partners to share the benefit, to establish a well rewarding system and communication mechanism, and to have a common consensus on quality management.

¡@¡@Because of recession of investment environment and deregulation of Mainland policies in Taiwan since the early 1990s, Taiwanese manufacturing industries were attracted with cheap production costs and regional development policies in Mainland China, led investment of Taiwanese manufacturing industries and export of Taiwan to Mainland China rose quickly. Since foreign investment policies had been changed, problems of labor shortages and rising wages got worse in Mainland China in recent years, led production advantages of Taiwanese manufacturing industries lost gradually. In order to look for supply chain process cheaply and effectively, Taiwanese manufacturing industries were developing toward localization and domestic market in Mainland China, led its¡¦ demands of Taiwanese supply chain reduced gradually. In order to increase importance of Taiwanese supply chain, Taiwan government should promote industrial restructuring and upgrading, and attract Taiwanese manufacturing industries establish R & D sectors about technology-intensive and knowledge-intensive in Taiwan. We can use advantages of logistics and channels about Taiwanese service industries, it will maintain and raise importance of Taiwanese supply chain by the high quality and high value-added part.

Quality Management (QM) and Supply Chain Management (SCM) have been considered as two of the most important business strategies. They have become the prerequisite for success and competitive advantage in the global market. Supplier Integration is a subset of supply chain, and supplier relationship is no longer a competition, but competition and cooperation. Integration capabilities between suppliers can be regarded as a competitive advantage. The better supplier integration capabilities, the better supply chain performance. That would further enhance the competitiveness of enterprises. This paper explores the relationship between QM practices and Supplier Integration of supply chains. The entire population of suppliers to aerospace industry in Taiwan was surveyed to measure use of QM practices. QM is modeled as a second-order construct reflected by six QM practices (small group problem solving, top management leadership for quality, information and feedback, process management, customer focus, and supplier involvement). The results showed supplier involvement is the only factor which has statistically significant effect on supplier integration. Our study reflects the underlying fact of the aerospace industry in Taiwan; i.e., it is a manufacturing industry with no design capability. For a manufacturing industry without design capability, supplier involvement is the most important construct for effective supply chain management.
