Pengelolaan bahan baku memiliki peran dalam meningkatkan keuntungan PT XYZ. Kondisi saat ini XYZ dihadapkan terjadi peningkatan permintaan terhadap readymix pada type K 225 akibat sudah dimulainya pembangunan di wilayah Kabupaten Madiun. Peningkatan perlu adanya perencanaan untuk mengatur kebutuhan baku. Pada penelitian menggunakan metode Material Requirement Planning (MRP) Penentuan lot MRP ti...

In order to closely adapt what they produce to what will be sold, it is mandatory for nowadays companies to make early decisions on the base of an uncertain production planning. We suggest a way to explicitly model the uncertainty and imprecision of the demand using possibility theory, all along the MRPII steps: Material Requirement Planning, Load Planning, Scheduling. Though propagation of thi...

This paper looks at the successes and disappointments of MRP. It studies numerous articles to determine what the key shortcomings of MRP are. Next, it investigates if these failures are correctable, and what the consequences of not correcting these de®ciencies means. This article considers alternatives that have been discussed in the current literature. Last of all this article discusses whethe...

It is an instinct requirement of the enterprise management to lower the cost so that the enterprise can optimize the asset efficiency. To enhance competition ability and enlarge the market share, enterprises must have a good inventory management system. In this paper, two solutions of inventory management based on bill of material (BOM) have been discussed. One is the accurate quantity and time...

The purpose of this paper is to present a polynomial time algorithm which determines the lot sizes for purchase component in Material Requirement Planning (MRP) environments with deterministic time-phased demand with zero lead time. In this model, backlog is not permitted, the unit purchasing price is based on the all-units discount system and resale of the excess units is possible at the order...

In this paper we develop a model for a capacitated production/ distribution network of general (but acyclic) topology with a general bill of materials, as considered in MRP (Material Requirement Planning) or DRP (Distribution Requirement Planning) systems. This model assumes stationary, deterministic demand rates and a standard stationary cost structure; it is a generalization of the uncapacita...
