Groundwater extraction in most Middle East and North Africa (MENA) countries far exceeds its renewability, which ranges from 6% to 100%. Freshwater resources support food production are very limited this region. Future climate predictions include more consistent longer wet periods with increasing surplus rainfall, will enhance flood flash occurrences the MENA. Demand management of groundwater m...

this paper develops a mathematical model using differential equations and considers a bullwhip effect in a supply chain network with multiple retailers and distributors. to ensure the stability of the entire system and reduce the bullwhip effect, a robust control method and an inventory replenishment policy are proposed. this shows that the choice of the output matrix may reduce the bullwhip ef...

The relationship between Taiwan’s groundwater resources recharge strategy and flood disasters is significant. adaptation strategies of traditional urbanization areas simulate the spatial distribution permeable pavements under different rainfall intensities that affect surface runoff infiltration. Since there are many parameters Stormwater Management Model set in low-impact development modules, ...

This paper tackles a generalization of the weight constrained shortest path problem in a directed network (WCSPP) in which replenishment arcs, that reset the accumulated weight along the path to zero, appear in the network. Such situations arise, for example, in airline crew pairing applications, where the weight represents duty hours, and replenishment arcs represent crew overnight rests, and ...

The replenishment staggering problem is the problem of offsetting inventory replenishment cycles of several items in order to minimize the maximum required storage space and/or other storage resources. In its simplest version, inventory consumption rates are constant over time and replenishment cycle lengths are known integer multiples of a given basic period. In this paper, a simple, efficient...

We study a non–cooperative game for joint replenishment by n firms that operate under an EOQ–like setting. Each firm decides whether to replenish independently or to participate in joint replenishment,and how much to contribute to joint ordering costs in case of participation. Joint replenishment cycle time is set by an intermediary as the lowest cycle time that can be financed with the private...

Abstract In this paper, we consider a combination of the joint replenishment problem (JRP) and single-machine scheduling with release dates. There is single machine one or more item types. Each job has date, positive processing time, it requires subset items. A can be started at time t only if all required types were replenished between date point . The ordering for distinct jobs combined. obje...

We analyze the interannual monthly variability of oxygen isotope ratios in data from IAEA stations along the Atlantic coast of South America between 238 and 348 S to evaluate the influence of parameters such as temperature, rainfall amount and moisture source contribution on meteoric water recharging two karst systems in subtropical Brazil. In addition, a 2 year monitoring program performed on ...

This paper deals with the determination of production-shipment policy for an integrated vendor-buyer system. The inventory model contains two decision variables: the replenishment lot size and the number of deliveries. This paper solves the inventory model considering two cases: 1) the replenishment lot size as continuous variable and the number of shipments as discrete variable, and 2) the rep...

The Bundelkhand region of Uttar Pradesh, India, is a parched region. Although long-term average annual rainfall the quite sufficient, yet, on short-term basis, experiencing sharp negative deviation in rainfall. was once densely forested area and considered cloud formation zone. present analysis shows that correlates with forest cover calls for paradigm shift region’s water resources management ...
