This paper concerns policy synthesis in large queuing networks. The results provide answers to the following questions: (i) It is well-known that an understanding of variability is important in the determination of safety stocks to prevent unwanted idleness. Is this the only use of high-order statistical information in policy synthesis? (ii) Will a translation of an optimal policy for the deter...
Exception handling is an important language feature for building more robust software programs. It is primarily concerned with capturing abnormal events, with the help of catch handlers for supporting recovery actions. In this paper, we advocate for a specification logic that can uniformly handle exceptions, program errors and other kinds of control flows. Our logic treats exceptions as possibl...
The pressure to reduce inventory investments in supply chains has increased as competition expands and product variety grows. Managers are looking for areas they can improve to reduce inventories without hurting the level of service provided. Two areas that managers focus on are the reduction of the replenishment lead time from suppliers and the variability of this lead time. The normal approxi...
This paper asks whether technology supported business processes currently used in supply chain management systems (SCMS) are equipped for maintaining business activity in times of crisis. It considers how SCMS accommodate the attempts of Western governments to introduce initiatives for preserving the food supply during pandemics or any other catastrophic event when there is an actual or potenti...
The paper is motivated by real problems encountered in a manufacturing and distribution process. We investigate the impact on the cost of safety stock in the supply chain of a product family in the context of re-engineering the manufacturing and distribution process. The pipeline hedging method is used to derive a model for estimating the safety stock cost in a supply chain. We use the concept ...

China’s urban household saving rate has increased markedly since the mid-1990s and the agesaving profile has become U-shaped. To understand these patterns, we analyze a panel of urban Chinese households over the period 1989-2009. We document a sharp increase in income uncertainty, largely due to an increase in transitory variance (the variance in household income attributed to transitory idiosy...
This thesis presents a model to determine safety stock considering the distinct planning parameters for a pharmaceutical company. Traditional parameters such as forecast accuracy, service level requirements and average lead-time are combined with a nontraditional upstream uncertainty parameter defined as supply reliability. In this instance, supply reliability measures uncertainty in the supply...
Producing companies aspire to availability despite appearing disruptions. To ens availability safety stocksare required. Howeversaf additional capital commitment and compensates d of solving the reasons.The intention is to increa production by configuring the production plan systematically. Thus the safety stock can be red proportion of inventory in producing companies i inventory, schedule dev...
