社会和谐：转型期社会建设的重要价值目标

社会和谐是指社会关系中的各种要素处于相互依存、相互协调、相互促进的状态，表现为人际关系和谐、人与社会关系和谐、人与自然关系和谐、人自身和谐四种形式。紧迫性、前瞻性和远景性是影响我国社会和谐的三种形态。因此，促进社会和谐，应从解决那些已经和正在危及社会和谐的问题．解决和消除那些可能危及社会和谐的隐患以及构建一种合理的社会结构三个层面着手。     

Individual efficiency and club performance: a panel analysis of professional baseball

This paper investigates whether players' individual‐ and club‐level efficiency has substantial impact on club performance in the Chinese Professional Baseball League (CPBL). Using data from 1990 to 2000, and a stochastic frontier model, we propose a different way to measure club‐level efficiency. Our empirical results indicate that club‐level efficiency is crucial to club performance, measured by the winning percentage. Although the literature shows that some inefficient clubs with abundant resources are still very successful on the diamond, our results confirm that club‐level efficiency has a moderate impact on the success of a baseball club in the CPBL.

Managing uncertainty in on-demand air travel

Fractional management companies (FMCs) that provide on-demand air travel services experience frequent changes in aircraft availability and flight requests. We propose scheduling heuristics which are both cost-effective and persistent (i.e., close to the original schedule) to address the uncertainty. The heuristics include pro-actively enforcing idleness of aircraft in creating the original schedule, strategically repositioning aircraft to serve yet-unknown demand and dense scheduling. Computational experiments are conducted in a simulator that mimics FMCs’ daily operations. Simulation results quantify the value of each heuristic, which can be easily incorporated into existing computational methods used in FMCs for static scheduling problems.     

A hybrid parallel genetic algorithm for yard crane scheduling

This paper aims at postulating a novel strategy in terms of yard crane scheduling. In this study, a dynamic scheduling model using objective programming for yard cranes is initially developed based on rolling-horizon approach. To resolve the NP-complete problem regarding the yard crane scheduling, a hybrid algorithm, which employs heuristic rules and parallel genetic algorithm (PGA), is then employed. Then a simulation model is developed for evaluating this approach. Finally, numerical experiments on a specific container terminal yard are used for system illustration. Computational results suggest that the proposed method is able to solve the problem efficiently.
