Development Of Model For Supplier Selection And Order Allocation With Discount Pricing And Expected Quality Loss

This paper discusses the development of optimization model for supplier selection and order allocation considering price discounts and quality of the components that are measured based on expectation of quality loss cost. The approach which was used quadratic loss function to estimated quality loss. The development of model is based on the drawback of previous research; where quality was measured only by defective components without considered to any loss of quality due to deviation from quality characteristics target. In the section of results and discussion of this paper is presented a numerical example in order to illustrate the implementation of proposed model. This numerical experiment performed by optimization software has indicated that the model able to generated optimal solution. Keywords- optimization model, supplier selection, price, discount, quality los

An Empirical Study of Furniture SMEs on Environment, Competitive Strategy, Manufacturing Strategy And Performance In East Java

The problem faced by the Indonesian furniture industry in general at this time is tight competition as a result of Indonesia's participation in the free market. Furthermore, the global financial crisis has raised the price of products and services more difficult to be reached by the majority of society. While, the problems faced by SMEs Furniture in East Java Province is the absence of a competitive strategy to overcome the low product quality, high production costs, as well as orders delivery time which is often not on time. This paper discusses an empirical study to solve these problems. Based on the analysis of the research model with Partial Least Squares method, it was obtained the following results. First, the dynamics of the environment affects competitive strategy based on differentiation. Two, competitive strategy will affect the choice of manufacturing strategy. Unfortunately, manufacturing strategy does not affect the performance of SMEs. Meanwhile, the dynamics of the environment will have a direct impact on manufacturing strategy. Finally, competing strategies directly affect the performance of SMEs furniture Keywords: furniture SMEs, competitive, manufacturing, performance, Partial Least Squares

Model Simultan Penentuan Toleransi Komponen Produk Rakitan dan Pabrik dalam Kolaborasi Manufaktur Make-to-Order

This paper discusses the development of simultaneous optimization model to determine component tolerance of assembly product and plant for manufacturing processes by considering quality tolerance limits, and delivery time constraint to minimize total cost in collaboration environment of make-to-order manufacturing systems. Total cost of the system consists of manufacturing costs and quality loss costs as the tolerance function, operational costs for multi-plant manufacturing collaboration which includes: setup costs, material handling costs, operating costs of assembly, manual operations costs, and transportation costs. Formulation of the model developed uses mixed integer non linear programming as a method of solution search. In the numerical examples presented, the optimization process results an optimal solution. Optimal solution is not sensitive if the changes in quality tolerance constraint and delivery time constraint is not large. While the addition of an alternative plant for producing a component can changes the alternative plant selecte

PENINGKATAN ADDED VALUE KOPRA PUTIH DENGAN METODA INDIRECT DRYING

Traditionally, drying of copra is carried out by sundrying or fumigation on a tomang (clay furnace). However, using these methods, the quality of copra resulted cannot be guaranteed and the prices is low, and thus the process is unprofitable. Another problem is that it is difficult to do the process during rainy season. We facilitated a copra home industry with a dryer with indirect drying system to replace the old copra processing drying equipment. The dryer consists of 12 racks equipped with a temperature controller (with temperatures reaching 150 ° C) and a timer. By controlling temperature and time it was possible to get good quality copra and the process can be done in rainy season. From the test results using LPG fuel at temperature of 70 ° C for 18 hours, white copra was produced with 7% moisture content
