摘要：Only a small set of employee scheduling articles have considered an objective of profit or contribution maximization, as opposed to the traditional objective of cost (including opportunity costs) minimization. In this article, we present one such formulation that is a market utility-based model for planning and scheduling in mass services (MUMS). MUMS is a holistic approach to market-based service capacity scheduling. The MUMS framework provides the structure for modeling the consequences of a...

摘要：This paper presents a theoretical framework for measuring volume flexibility and relating these measures to firm performance. We develop four metrics using the principle that a volume flexible firm can handle similar levels of uncertainty (as measured by sales variability) with smaller fluctuations in inputs (as measured by variability in cost of goods sold and variability in inventory levels). Then, using 20 years of Compustat data on 550 firms in the capital goods industry, we find that on t...

摘要：We explore theoretically and empirically how efforts to enhance environmental performance may enable other types of manufacturing improvements. Drawing on a unique data set comprised of detailed surveys of 42 automotive assembly plants, associated quality metrics, and in-depth qualitative data from 17 automotive assembly plants, we show that attaining superior environmental performance can be a significant driver of superior quality. We highlight the synergistic and reciprocal nature of enviro...

摘要：This paper explores the relationship between environmental practices and performance in services and the impact of such practices on the external portion of the service profit chain. Using structural equation modeling, it tests the hypotheses developed with data from the European hospitality industry. The findings suggest that environmental practices are positively related to performance through the mediating effect of enhanced customer satisfaction and loyalty. The paper's contributions. incl...

摘要：To date, it is unclear as to how Environmental Management Systems (EMS) are implemented and what effects these systems have on other environmental and operational practices. This study reports empirical insights to EMS practices based on the largest EMS survey of manufacturing firms in the United States. The objective of the study is to test for a relationship between environmental management systems and perceived operations performance while considering direct and indirect effects of various ...

摘要：We study the deterministic time-varying demand lot-sizing problem in which learning and forgetting in setups and production are considered simultaneously. It is an extension of Chiu's work. We propose a near-optimal forward dynamic programming algorithm and suggest the use of a good heuristic method in a situation in which the computational effort is extremely intolerable. Several important observations obtained from a two-phase experiment verify the goodness of the proposed algorithm and the ...

摘要：ISO 14001 constitutes a major dilemma for many American firms. This new standard holds the promise of waste reduction and better process management, but the benefits and costs are very difficult to predict. This study attempts to identify and explain antecedents impacting the decision to pursue certification for some of the first plants certified in the United States. Using data from a large survey of U.S. managers and a Logit analysis, we find the factors influencing management decisions to a...

摘要：An important issue being discussed for Chilean pine plantation policies is the application of environmental protection measures when managing its timber areas. Typical measures, already in place in more developed countries, include imposing riparian strips and protecting fragile soils from the use of heavy machinery. While environmental protection measures have been considered vital for decades, so far there has been almost no attempt to quantify both the benefits and costs of these measures. ...

摘要：In this paper we review the literature on appointment policies, specifically in terms of the objective function commonly used and the assumptions made about the behavior of demand. First, we provide an economic framework to analyze the problem. Based on this framework we make a critical analysis of the objective functions used in the literature. We also question the validity of the assumption made throughout the literature that demand is exogenous and independent of customers' waiting times. W...
