This paper discusses Economic Production Quantity (EPQ) model with defective items and shortage, which is a review from the article Krishnamoorthi & Panayappan [International Journal of Management Science and Engineering ...
• (2016-05-23)
This article studies the economic production quantity (EPQ). During the pro- duction process, the failures occur and reworking is conducted to minimize the total production cost. During the reworking process or production ...
• (perpustakaan UR, 2021-09)
This article discusses the problem of solving supply by considering a product that has a limited shelf life called deterioration. This study also considers the existence of product deficiencies and partial backlogging ...
• (2013-03-26)
This paper discussed about the formulation of the total cost of the average inventory on inventory models using linear functions, where the levels of demand and production are limited. In the model inventory, total cost ...
• (2021-04)
This paper discusses the trapezoidal fuzzy numbers transportation problem with one point approach to optimize. The coefficents of cost, supply and demand are a fuzzy number that appears because there are uncertainty that ...
