International Rice Baseline with Deterministic and Stochastic Projections, 2012-2021

Wailes, Eric J.; Chavez, Eddie C. - Department of Agricultural Economics and Agribusiness, … - 2012

This publication contains recent baseline projections from the Arkansas Global Rice Economics Program (AGREP) for U.S. and international rice economies. These projections serve as a baseline for evaluating and comparing alternative macroeconomic, policy, weather, and technological scenarios....

Optimal Goodwill Model with Consumer Recommendations and Market Segmentation

Bogusz, Dominika; Gorajski, Mariusz - Wydział Ekonomiczno-Socjologiczny, Uniwersytet Łódzki - 2014

We propose a new dynamic model of product goodwill where a product is sold in many market segments, and where the segments are indicated by the usage experience of consumers. The dynamics of product goodwill is described by a partial differential equation of the Lotka–Sharpe– McKendrick...

New Bounds for the Identical Parallel Processor Weighted Flow Time Problem

Webster, Scott - In: Management Science 38 (1992) 1, pp. 124-136

In 1964, Eastman, Even, and Isaacs (EEI) presented a polynomial time lower bound for the NP-hard problem of scheduling n jobs on m available and identical processors to minimize weighted flow time. A general bound, of which the EEI bound is a special case, is proposed. Four new bounds for the...

Analysis of the Deterministic (s, S) Inventory Problem

Iyer, Ananth V.; Schrage, Linus E. - In: Management Science 38 (1992) 9, pp. 1299-1313

demand distribution may have been obtained by fitting it to some historical demand stream. In contrast, the deterministic (s … stream, bypassing the distribution fitting step. The deterministic (s, S) inventory problem thus chooses parameters s and S … for finding an optimal (s, S) for the deterministic problem, and (b) an empirical comparison of the two approaches. In (b …

A wind–diesel system with hydrogen storage: Joint optimisation of design and dispatch

Garcia, Raquel S.; Weisser, Daniel - In: Renewable Energy 31 (2006) 14, pp. 2296-2320

We compare two models to determine the size of grid units and dispatch in a wind-diesel power system with hydrogen storage. Both take as data 1-year time series of hourly wind speed and electricity demand, and their objective is to minimise cost. Our first model, based on linear programming,...

Estimation of the efficiency of Japanese hospitals using a dynamic and network data envelopment analysis model

Kawaguchi, Hiroyuki; Tone, Kaoru; Tsutsui, Miki - In: Health Care Management Science 17 (2014) 2, pp. 101-112

The purpose of this study was to perform an interim evaluation of the policy effect of the current reform of Japan’s municipal hospitals. We focused on efficiency improvements both within hospitals and within two separate internal hospital organizations. Hospitals have two heterogeneous...

The Shifting Bottleneck Procedure for Job Shop Scheduling

Adams, Joseph; Balas, Egon; Zawack, Daniel - In: Management Science 34 (1988) 3, pp. 391-401

We describe an approximation method for solving the minimum makespan problem of job shop scheduling. It sequences the machines one by one, successively, taking each time the machine identified as a bottleneck among the machines not yet sequenced. Every time after a new machine is sequenced, all...

Priority Rules for Job Shops with Weighted Tardiness Costs

Vepsalainen, Ari P. J.; Morton, Thomas E. - In: Management Science 33 (1987) 8, pp. 1035-1047

Mainstream research in priority dispatching has considered jobs with equal delay penalties, thereby ruling out strategic differentiation of customer orders. We develop and test efficient dispatching rules for the weighted tardiness problem with job-specific due dates and delay penalties. Our...
