Two conditions are discussed: the first is when the product life cycle ends in the production stage and the second is when the product life cycle ends in the non-production stage. We develop a genetic algorithm to find the optimal period time and the lowest expected total

Questionnaires are then sent to a selected list of SMT companies in Taiwan. The data are then analyzed through statistical methods. Additionally, the factor analysis is used to extract major components and construct the evaluation criteria, which includes five main categories and 41 evaluation indicators. The Strengths, Weakness, Opportunities, and Threats (SWOT) analysis is also used to consider factors that affect strengths, weaknesses, opportunities, and threats of logistics in a firm. Those factors include competitions between the existing competitors, threats from potential entrants, and threats from the alternatives. The five forces analysis is conducted to survey the bargaining power of the buyers. The study compiles views and recommendations from supplier management profession...

This paper develops a model to simultaneously determine the inventory and pricing policies of a retailer with contractual agreement. The replenishment plan, pricing policy, and schedule of the special sale plan with future purchasing price increase and incentive demand are considered in a deteriorating item inventory model with a finite planning horizon. We provide a comprehensive analysis to derive the optimal special sale period, the optimal number of deliveries and the optimal retailer’s selling price. A numerical example is presented to demonstrate the theory. The results show that demand rate, price and other incentive policies are critical in managing deteriorating inventories.

Base on an empirical study through questionnaires, we investigate the supplier management and critical success factors of the Taiwanese enterprises. It is shown that different industries deploy different outsourcing strategies. Organizations should have a good working relationship with their suppliers as well as with their customers, and the enterprises adopting different export rates should deploy different outsourcing strategies too. The most important issues of supplier management include supplier capability to deliver on time, long term contract strategy with suppliers, supplier evaluation, and quality of material from suppliers.

Buyer asks the vendor to deliver products in small batch with discrete delivery order. The problem is modeled as a Mixed Integer Non Linear Program (MINLP) with constraint. Langrangen method and branch and bound procedure are developed to solve the problem. One numerical example is shown to illustrate the model and solution procedures and the result shows that the Lagrangean solution approach can derive global optimum solution.

The line is important for large-sized products, such as trucks, buses and cars. In this paper, we proposed a mathematical model for two-sided assembly line type II (TALBP-II) with assignment restrictions. The aim of the model is minimizing the cycle time for a given number of mated-workstations and balancing the workstation simultaneously. The model provides a more realistic situation of the two-sided assembly line problems. Genetic algorithm and iterative first-fit rule are used to solve the problem. The performances of both methods are compared using six numerical examples. Based on the experiments, the iterative first-fit rule can take the advantage of finding the best position over many workstations and the genetic algorithm provides more flexible task assignment and is significantly faster than the iterative first-fit rule.

It focuses on a consumable probe card used in the semiconductor wafer testing operation. Referring to the relevant resources and the semiconductor testing operation, a fundamental concept is built to develop a probe card management system. Design/methodology/approach –

Extensions to allow backorders are done for the EOQ/EPQ models. In contrast to previous literatures, limiting values on a finite planning horizon are used rather than algebraic manipulations for the cost function comparisons.

We develop a deteriorating inventory replenishment model of the system and present an algorithm to derive the retailer's optimal replenishment cycle, shortage period, order quantity and the supplier's managing cost. Numerical example and sensitivity analysis are given to illustrate the model.

This paper extends Moon and Lee's model to examine a production system with a random life cycle. Two conditions are discussed: the first is when the product life cycle ends in the production stage and the second is when the product life cycle ends in the non-production stage. We develop an algorithm to derive the optimal period time and expected total cost. Numerical examples and sensitivity analyses are given to validate the results of the production model.
