Price coordination in a three-level supply chain with different channel structures using game-theoretic approach / Yun Huang in International journal of management science and engineering management, Vol. 5 N° 2 (Avril 2010) 

Public ISBD [article]  in International journal of management science and engineering management > Vol. 5 N° 2 (Avril 2010) . - pp.83-94 Titre : Price coordination in a three-level supply chain with different channel structures using game-theoretic approach Type de document : texte imprimé Auteurs : Yun Huang, Auteur ; George Q. Huang, Auteur Année de publication : 2011 Article en page(s) : pp.83-94 Note générale : Management Langues : Anglais (eng) Mots-clés : Multi-level  supply  chain  Pricing  Channel  structure  Stackelberg  game  Nash  game Résumé : Pricing is an important decision affecting the profitability of the supply chain system and individual channel members. It is important to coordinate pricing decisions for different channel members of the supply chain under different channel structures and power structures. Most studies to date have focused on price coordination in the traditional channel structure, mostly composed of two echelons. Little attention has been given to the multi-level channel. This paper studies price coordination problem in a threelevel supply chain composed of a single supplier, a single manufacturer and a single retailer. Three types of channel structures are considered, namely, the decentralized, the semi-integrated, and the integrated. Two power structures are studied for the decentralized and the semi-integrated channels. The leader-follower power structure is modeled as a Stackelberg game, where the manufacturer always takes the leadership, while the independent power structure is treated as a simultaneous non-cooperative game (simply Nash game). We explore the effects of power structures, channel structures and market parameters on equilibrium prices and profits. The results show that the manufacturer or the integrated members had better take the channel leadership. We also find that the integration for the manufacturer and the retailer cannot always improve their profits in a monopoly. Besides, when product cost is larger than a certain level, the chain members’ profits will increase as the market becomes more sensitive to the retail price.

Response surface methodology for minimizing solder-ball defects in an electronics-assembly process / Chuvej Chansa-ngavej in International journal of management science and engineering management, Vol. 5 N° 2 (Avril 2010) 

Public ISBD [article]  in International journal of management science and engineering management > Vol. 5 N° 2 (Avril 2010) . - pp.95-100 Titre : Response surface methodology for minimizing solder-ball defects in an electronics-assembly process Type de document : texte imprimé Auteurs : Chuvej Chansa-ngavej, Auteur ; Jumroon Kasemsomporn, Auteur Année de publication : 2011 Article en page(s) : pp.95-100 Note générale : Management Langues : Anglais (eng) Mots-clés : Response  surface  methodology  Reflow-thermal  profile  Solder-ball  defects  Process  optimization Résumé : Electronics-assembly companies are always trying to reduce solder-ball defects as their customers keep tightening specification since the solder balls could cause electrical short circuit and damage to the product. The effect of solder ball defects is not only on quality risk, but also on scrap costs. One initiative to overcome this problem is to minimize the spattering of solder while the product is passing through reflow-soldering oven. Reflow soldering is a complex process, which requires specific optimal soldering conditions based on experimental data. The trial-and-error method to determine the optimal conditions would require a prohibitively large number of experiments, however. Therefore, the Response Surface Methodology (RSM) was employed in this research to overcome this problem. The main idea of RSM is to use a set of designed experiments to obtain the optimal response. The second-order model was used here. The ramp-up rate and pre-heat time of reflow-thermal profile were selected as the input variables, and the number of solder-ball defects was the output variable. This research project has resulted in US$1,094 monthly cost savings under the set optimal conditions, which are 1.4 ˚C/s of ramp-up rate and 60 s of pre-heat time. At this rate the project is paid back in less than a month. Apart from the tangible benefit, other intangibles were also gained as lessons learned from the implementation of this methodology could be extended to other products.

Literature reviews on the issue of transforming services into products have first been conducted for getting the comprehensive picture on the complex topic. The empirical part of the study consists of expert interviews in eight different organizations representing the Finnish technical engineering and consulting industry. According to the study, only few companies have actually productized their services in the technical engineering and consulting industry this far. The service product was seen to consist of the modulated service package and the implementation process. The product development process was seen difficult to define. However, some general, but very important, phases can be withdrawn from the study. On the basis of integration of theoretical frameworks and results of the empirical study, we propose the product development process for the knowledge-intensive technical engineering and consulting firms.

Navid Kasirian, Auteur ; Rosnah Mohd. Yusuff, Auteur ; M. Y Ismail, Auteur Année de publication : 2011 Article en page(s) : pp.125-135 Note générale : Management Langues : Anglais (eng) Mots-clés : Supplier  selection  Interdependencies  Decision  makers  Analytic  hierarchy  process  Analytic  network  process  Preemptive  goal  programming Résumé : Most organizations prefer to outsource the activities which are not cost-efficient. With regard to the huge amount of expenditure in this area, proper selection of the desirable suppliers becomes significant. Previous studies indicated that the criteria of supplier selection might not be always independent, and this fact implies the existence of interdependencies among them that may affect the supplier selection. This study presents and compares two multi-attribute decision making (MADM) techniques to deal with the supplier selection problem with and without interdependency. An Analytic Hierarchy Process (AHP), and its extension, Analytic Network Process (ANP) are applied to find the final priorities of the suppliers respectively for the cases of independency and interdependency in an automotive manufacturing company. The two techniques lead to different rankings for the potential suppliers. Thus, a Preemptive Goal Programming (PGP) with two goals, maximizing the Total Value of Purchasing and minimizing the Total Cost of Purchasing, to decide which method is the best was conducted. The whole process is illustrated in a case study. The results from the company of the case study showed that the ANP had the optimal TCP of 1,290 US dollars, while the value for AHP was 1,710 USD. However, comparing the TVP value for the two methods shows a negligible difference.

A fuzzy logic-based approach to idea screening for product design / Yao-Tsung Ko in International journal of management science and engineering management, Vol. 5 N° 2 (Avril 2010) 

Public ISBD [article]  in International journal of management science and engineering management > Vol. 5 N° 2 (Avril 2010) . - pp.149-160 Titre : A fuzzy logic-based approach to idea screening for product design Type de document : texte imprimé Auteurs : Yao-Tsung Ko, Auteur Année de publication : 2011 Article en page(s) : pp.149-160 Note générale : Management Langues : Anglais (eng) Mots-clés : New  product  development  (NPD)  Fuzzy  synthetic  evaluation  method  (FSEM)  Fuzzy  sets  theory  Product  design Résumé : The idea screening of a new product concept is perhaps the most critical activity in new product development (NPD). This paper presents a fuzzy synthetic evaluation method (FSEM) for selecting an optimum design alternatives based on fuzzy set theory. The process involves constructing a hierarchical objective, setting evaluation criteria, establishing a fuzzy judgment matrix and weight vector, and then ranking the order of design alternatives by a fuzzy number in the fuzzy sequencing vector. A hierarchical structure is used to calculate the fuzzy probability level by level from the lowest-level objectives. The evaluation objectives are arranged in the hierarchical structure with several levels. The relative contribution of each objective to the overall value of the solution and the rating or degree of approximation of a solution with respect to a given objective are quantified with the membership functions of a fuzzy set. After the fuzzy expected values of the top-level objectives are calculated, they are then used to make a decision quantitatively on selecting the optimal design alternative. The proposed approach can efficiently aid managers in dealing with both ambiguity and complexity in product screening decisions. To verify the feasibility of this approach, a case study is conducted with a product design of Power Line communication (PLC) in this study.
