The majority of publications in the scientific literature investigate stochastic demand processes with constant order lead times. In practice, inventory management software like MRP is used by companies even if ignored uncertainty this work, we influence type and existing solutions proposed literature. To do this, ARTIREV tool to identify major schools thought competing filed highlight current ...

groundwater is one of the common resources in varamin plain, but due to over extraction it has been exposed to ruin. this phenomenon will lead to economic and environmental problems. on the other hand, the world is expected to face with more stochastic events of water supply. furthermore, incorporating stochastic consideration of water supply becomes more acute in designing water facilities. th...

This study investigates the single-vendor single-buyer integrated production inventory models with controllable lead time. The lead time demand is stochastic and shortage during the lead time is permitted. The buyer orders a lot of size Q and the vendor manufactures mQ with a finite production rate P at one set-up but ships in quantity Q to the buyer over m times. Most researchers do not take t...

We consider a single-echelon, single-item inventory system where both demand and lead-time are stochastic. Continuous review policy is used to control the inventory system. The objective is to calculate the reorder point level under stochastic parameters. A case study is presented in Neonatal Intensive Care Unit. Keywords—Inventory control system, reorder point level, stochastic demand, stochas...

In this paper, we describe the first computationally efficient policies for stochastic inventory models with lost sales and replenishment lead times that admit worst-case performance guarantees. In particular, we introduce dual-balancing policies for lost-sales models that are conceptually similar to dual-balancing policies recently introduced for a broad class of inventory models in which dema...

to evaluate the effect of application of municipal solid waste compost (mswc) on the accumulation of heavy metals of lead, nickel and cadmium in the soil under maize cultivation, a factorial experiment in base randomized complete block design (rcbd) with four different amounts of municipal solid waste compost (zero, 15, 30 and 60 tons ha-1) and time (compost applied once or twice) was performed...
