We present a structural econometric framework of supply chain information flows. The framework analyzes supply chain black boxes by measuring how input demand signals transform into output order signals. It characterizes inventory policies with impulse response functions (IRFs). We develop an algorithm to estimate these IRFs, and the structural parameters underlying them, with single firm sales...

Although supply chain (SC) has gained increasing attention in the last two decades and numerous SC problems have been identified and solved, there is a lack of systematic approach to solve SC problems in an uncertain environment. Since past data are not always available or reliable due to market durbulance, the sources of uncertainty (e.g. lead time, demand rate, inventory costs and backorder c...

In this paper, we develop dissipativity notions for dynamical systems with discontinuous vector fields. Specifically, we consider dynamical systems with Lebesgue measurable and locally essentially bounded vector fields characterized by differential inclusions involving Filippov set-valued maps specifying a set of directions for the system velocity and admitting Filippov solutions with absolutel...

In today's economy, it is no longer business versus business, but rather supply chain versus supply chain. To compete, supply chain members must learn to seamlessly integrate, grow, and develop business functions. Traditional quality management practices have been and will continue to be used to address many of these supply chain integration issues. With this in mind, current managerial thinkin...

The paper deals with the Supply Function Equilibrium (SFE) as a model of competition in electricity markets. It introduces theoretical advancement through relaxing traditional assumptions of continuity of supply functions and provides a foundation for efficient computational algorithms. Special emphasis is placed on exploring the existence of equilibria and on the players’ ability to learn subj...

Background With support from USAID-funded projects, the Dominican Republic (DR) started organizing a unified pharmaceutical system (SUGEMI) in 2010. Implementing SUGEMI included developing standard operating procedures (SOPs) for all system components, appointing personnel for national and regional pharmaceutical units, and training on-site staff responsible for pharmaceutical supply management...

In this chapter, we shall review plant responses to changes in supply of the two inorganic N sources nitrate (NO3 ) and ammonium (NH4 +), with an emphasis on primary mechanisms of transport, and their regulation. The topics discussed here include: soil N resources and their ecological implications for plant life; parallel responses in plant growth and N transport activity as functions of N supp...

In this article, we present estimates of regional softwood lumber supply functions in the United States using annual time series data for 1959 to 2009. Seemingly unrelated regression is used in a profit maximization framework to model softwood lumber supply as a function of lumber and stumpage prices, lagged supply, wage rate, and interest rate for the eastern and western United States. The eff...

A voltage reference using a depletion-mode device is designed in a 0.13μm CMOS process and achieves ultra-low power consumption and sub-1V operation without sacrificing temperature and supply voltage insensitivity. Measurements show a temperature coefficient of 3.6ppm/C, line sensitivity of 0.033%/V, power supply rejection ratio of -67dB, and power consumption of 2.2pW. It requires only two dev...
