摘要：Kanban-controlled serial manufacturing systems have been popular in Japan for many years. The analytical intractibility of such systems makes simulation and heuristics essential in studying them. In this paper we develop some theoretical results-reversibility and dominance-that characterize the dynamics of these systems, provide insight into their behavior and help greatly reduce the simulation effort needed to study them. These structural results also provide the basis for developing heuristi...

摘要：High-Definition Television promises to be the next generation of television. This technology has broad implications for consumer markets, as well as the underlying manufacturing, technology development, and R&D activities of firms. Under increasing pressure from various groups, the U.S. government must make major policy and funding decisions based on its assessment of the likely demand for HDTV. Three published reports which forecast sales of HDTV after its scheduled introduction in the mid-19...

摘要：This study examines the linkages between relatedness and synergy in the context of diversification among U.S. pharmaceutical firms for the period 1960-1980. Rather than assume (as in the entropy, Herfindahl and concentric indices of diversification) that the levels of synergy generated by different related combinations of business units are identical, we estimate synergy directly using a modified version of the concentric index. In addition to estimating synergy using capital market performanc...

摘要：Drawing on recent developments in discrete time fixed income options theory, we propose a stochastic programming procedure, which we call stochastic dedication, for managing asset/liability portfolios with interest rate contingent claims. The model uses scenario generation to combine deterministic dedication techniques with stochastic duration matching methods, and provides the portfolio manager with a risk/return Pareto optimal frontier from which a portfolio may be selected based on individu...
