Supply chain strategy for high technology-content product and its consequences to technology transfer mechanism

The purpose of this article is to develop supply strategy of a company producing high technology-content product and subsequently to analyse the consequences of the strategy on technology transfer process that takes place on the company itself or between the company and its suppliers. Taking into consideration the extensive impact of globalisation on companys operation activities, the article focuses on Vertical Integration and Local Suppliers strategies on behalf of supply strategy in the global environment. Four supply chain factors are considered in the selection process of these two supply strategies, namely, country environment, competitive situation, company characteristic and extent of globalisation. Finally, this article describes dominant mechanisms of technology transfer as consequences of supply strategy.

The impact of learning on assembly line capacity (A case study of an Indonesia car factory)

Learning curve has been known as a method to describe the learning capability of an organization. This paper will investigate the impact of learning to assembly line capacity. A case study has been conducted in one of major car manufacturers in Indonesia. It produces variants of products and implements a mixed model assembly line. The purposes of this research are to identify the learning curve model and investigate its impact to assembly line capacity. This paper applies log-linear model as a reference to construct the learning curve models and calculate their learning rate. It will be used to estimate the actual capacity of assembly line. The study shows that the actual capacity is lower than the designed capacity.

Maximum quantity determination inventory policy for fast-moving products in convenience store distribution center

This paper evaluated the distribution centers performance of X Company (later on is referred as X Co.). As one of the major companies that have activities in the field of product distribution and sales of Fast Moving Consumer Goods (FMCG), X Co. required in order to meet customer needs and demands. The phenomenon of over-stock and out of stock occurring in DC make identifying the root cause must be traced. Main objective of this research is to determine appropriate inventory policy in DC, in order to maintain the supply of stock and improve the service level of distribution centers. Perpetual policy (Q model) is proposed to be the most suitable yet applicable model for X Co. Determination of the maximum quantity originally done intuitively without correct standardized Q Model. As a result, service level increased from 68% to 96.6% for all 170 simulated items in June 2013.

3-Echelon distribution policy with order flexibility and direct ordering system

This paper considers a three-echelon supply chain inventory problem consisting of single manufacturer, distributor and retailer. In the system under discussion, the manufacturer produces a product and supplies it to the distributor and it is also allowed to direct shipping to supplier facing a deterministic demand but the time span of delivery is relatively short. We develop some scenario to accommodate special policies that minimizes the total cost and subsequently taking into account the loss of flexibility in the condition when the size of order quantity is too big. Model development discussed in this paper is to enable the model to choose not only the distributor but also the manufacturer as a candidate of supplier. The objective function is to minimize the total expected cost of the system. An algorithm is developed to obtain the optimal solution and a numerical example is also included to show the results of the proposed model.
