W study the safety stock positioning problem in single-product multistage supply chains with tree network structures, where each stage controls its inventory using an installation continuous-time base-stock policy. External demands follow independent Poisson processes, and unsatisfied demands at each stage are fully backordered. The processing (e.g., production) cycle times and transportation l...

Context NXP operates in a highly dynamic and globalized semiconductor market. The NXP supply chain control is like it peers in semiconductor business quite complex. To manage the supply chain and to deal with the market characteristics, six so called Business Renewal II objectives were launched as part of the one page strategy. On one hand the BR II objectives target for a lower break-even poin...

Cost effective supply chain management under various market, logistics and production uncertainties is a critical issue for companies in the chemical process industry. Uncertainties in the supply chain usually increase the variance of profits (or costs) to the company, increasing the likelihood of decreased profit. Demand uncertainty, in particular, is an important factor to be considered in th...

This paper is centered around the design of a threadand memory-safe language, primarily for the compilation of application-specific services for extensible operating systems. We describe various issues that have influenced the design of our language, called Cuckoo, that guarantees safety of programs with potentially asynchronous flows of control. Comparisons are drawn between Cuckoo and related...

OBJECTIVE To test the hypothesis that comprehensive efforts to reduce a workforce's health and safety risks can be associated with a company's stock market performance. METHODS Stock market performance of Corporate Health Achievement Award winners was tracked under four different scenarios using simulation and past market performance. RESULTS A portfolio of companies recognized as award win...

Traditionally, inventory management experts have calculated a fixed economic order quantity (EOQ) that minimizes the cost of ordering and keeping stock. Some organizations use fixed maximum and minimum order quantity (MOQ) which ranges around EOQ for stocking various parts. These quantities are ordered at a specific stock level called the reorder point. The reorder point is calculated as the st...

We consider a multi-stage production/distribution supply chain subject to stochastic demand. We formulate an optimization problem to determine where to place decoupling inventories, so-called strategic inventories, across the supply chain so as to minimize inventory holding costs subject to a service constraint for satisfying customer demand. We assume demand is normally distributed. For each s...

Previous analyses of a large ensemble of stock markets have demonstrated that a log-periodic power law (LPPL) behavior of the prices constitutes a qualifying signature of speculative bubbles that often land with a crash. We detect such a LPPL signature in the foreign capital inflow during the bubble on the US markets culminating in March 2000. We detect a weak synchronization and lag with the N...

The stock versus flow effect of the federal debt/deficit on a real interest rate is examined in a reduced-form equation. The evidence shows a positive and significant linkage between the federal debt and an ex-post, taxadjusted, short-term, real interest rate.

Within the non-stochastic dynamic general equilibrium model framework this paper examines the implications of alternative fiscal consolidation programs for small open economy. The calibrated model enables realistically quantify the impact of the deficit financing and fiscal consolidation on consumption and saving of households, investment of firms and thereby on the capital stock and real inter...
