Abstract

Inventory control systems have an important role in supply chain management to control process of production, inventory and distribution of products in accordance with rapidly changing consumer demand. The research aims to develop inventory control system on supply chain that can manage the number of production and supply of products based on variables of consumer demand and lead time. Supply chain inventory control systems are designed using model of supply chain inventory control within the information system framework. Model of inventory control using variable of demand lead time is designed by  probability approach. Input to the system are data of demand and lead time sent by retail. The results of research provide theory of supply chain inventory control system with probability approach, especially on developing the theory of probability distribution for combined variables from  two random variables of normal distributed.  Inventory control system used to determine safety stock and reorder point as the basis for determining  the replenishment stock. Furthermore by the system, supply chain management can manage the estimation of production number, and manage inventory and stock number of products in warehouse, supplier and retail in accordance with the consumer demand.

Abstract

A wave runrup height on a coastal structure with sloping face is one ofthe considerations in the planning and design of sea—walLs or brealcwaters. In this paper, a wave run—up height on rock slopes of a coastal structure is presented using the empirical approach based on incident waves entering coastal structure. A height and increasing level of wave run-up hom incident wave amplitude are presented on rock slopes of a coastal structure with various angle of structure slopes and various water depths. The influence of incident wave height and wave period on the wave run-up height are described through the correlation analysis, and the probability distribution of wave run-up height is described as a Weibull distribution.

Abstract

A knowledge of wave run-up behavior on a coastal structure is one of the most important factors affecting the design of coastal structures exposed to wave attack. Prediction of wave run-up on a coastal impermeable structure with slope face and various friction factors are discussed with simplifying assumptions. An analytical approach is given for predicting wave run-up based on data measurements as the parameters of  incident waves entering to coastal structure.  Statistical approach with Weibull distribution is given on prediction of wave run-up, and present the probability distribution of wave run-up height.
