Keunggulan kompetitif sebuah bisnis banyak menjadi bahasan di industri dan akademis. Salah satunya kemampuan memenuhi permintaan dengan jumlah yang tepat, waktu tepat lokasi tepat. Persediaan hadir dalam peningkatan keunggulan tersebut bagian terpenting pemenuhan produk. Model perencanaan pengendalian persediaan klasik seperti EOQ/ EPQ, telah memberikan kontribusi permintaan. Dengan asumsi-asum...

Several authors have developed models for the EOQ when only a percentage of stockouts will be backordered. Most of these models are complicated, with equations unlike those for the EOQ with full backordering. In this paper we extend work by Pentico and Drake [The deterministic EOQ with partial backordering: a new approach. European Journal of Operational Research 2008; in press] that developed ...

In this article, manufacturer-retailer supply chain coordination (SCC) has been developed under periodic review inventory system. In the studied model, the retailer as downstream member uses periodic review inventory policy and decides about review period (T) and order-up-to-level (R). Also, the manufacturer as upstream member faces EPQ system and determines the number of shipments from manufac...

Carbon and Sulfur dioxides emissions are the key issues of global warming that affects on human health. Emissions cap- -trade policy is a mechanism implemented in several countries to reduce emissions. Nowadays, public gathering restricted due pandemic situation caused by COVID-19. As result, people facing huge problems their regular activities lifestyle. During lockdown periods, demands for fe...

In this paper, we have developed an economic production quantity (EPQ) model in which is executed mainly by the original machine. But when system faces disruption, buffer of it continues production. Here, incorporate a fixed Safe Period running policy, machine runs interruptedly, whenever commences. The disruption may occur at any moment time horizon over safe period, and then, will go under co...

This paper presents the economic production quantity (EPQ) models for the imperfect quality items produced with/without the presence of shortage condition. The models are presented in a two-level supply chain composed of a single manufacturer and a single buyer to investigate the performance of vendormanaged inventory (VMI) policy. The total costs are minimized to obtain the optimal production ...

The recent advances in manufacturing systems motivate several studies to focus on Economic Production Quantity (EPQ) problem. Althuogh there are several extentions to the EPQ, this paper provides a new extension by considering some of the real world parameters like: (a) shortages in the form of partial backordering, (b) inventory can deteriorate stochastically, (c) machine can break down stocha...

This paper deals with an economic production quantity (EPQ)model for deteriorating items with price and advertisement dependent demand. We have considered three types of continuous probabilistic deterioration functions to determine the total inventory cost. Here, the rate of replenishment is considered to be a variable and the generalized unit production cost function is formulated by incorpora...
