چکیده

Inventory or material balance control is an important part of process control. In the literature, many rules have been proposed to help in designing such systems, but their justification is often unclear. The main contribution of this paper is to propose the more general localconsistency rule for evaluating inventory control systems. Consistency means that the steadystate mass balances (total, component and phase) for the individual units and the overall plant are satisfied. In addition, local-consistency is a desired property, meaning that the local mass balances are satisfied with local inventory loops only.

Microeconomic Inventory Adjustment: Evidence from U.S. Firm-Level Data

We examine inventory adjustment in the U.S. manufacturing sector using quarterly rmlevel data over the period 1978{97. Our evidence indicates that the inventory investment process is nonlinear and asymmetric, results consistent with a nonconvex adjustment cost structure. The inventory adjustment process di ers over the business cycle: for a given level of excess inventories, rms disinvest more ...

Inventory and Price Control under Time-consistent Coherent and Markov Risk Measure

We use time-consistent coherent and Markov risk measure to study a risk-averse firm’s inventory and price control activities. Our dynamic programming model leads to optimal policy structures that are reminiscent of their risk-neutral counterparts. However, with risk aversion there emerge new patterns. First, monotone properties are derivable for the pricing policy when the convex risk set assoc...

Inventory and Price Control under Time-consistent Coherent and Markov Risk Measure–Unabridged Version

We use the recently proposed concept of time-consistent coherent and Markov risk measure on the study of a risk-averse firm’s inventory and price control activities. In our shock-driven setting which is different from the state-driven setting where the measure is first introduced, we show the suitability of dynamic programming formulations. On this basis, we examine pure inventory and joint inv...
