浅析任务引领教学方法中任务的设计

在职业院校的课程教学方法改革中,任务引领式教学法是较好实现工学结合的一种方法,绝大部分教师都想应用这种方法进行教学,培养更多满足社会需求的高素质技能型人才,但在如何设计教学任务、教学任务的类型有哪些、教学任务从何处来等问题,不少教师心中无底。     

Non-permutation flowshop scheduling in a supply chain with sequence-dependent setup times

In this paper, we consider a flowshop scheduling problem with sequence-dependent setup times and a bicriteria objective to minimize the work-in-process inventory for the producer and to maximize the customers' service level. The use of a bicriteria objective is motivated by the fact that successful companies in today's environment not only try to minimize their own cost but also try to fulfill their customers' need. Two main approaches, permutation and non-permutation schedules, are considered in finding the optimal schedule for a flowshop. In permutation schedules the sequence of jobs remains the same on all machines whereas in non-permutation schedule, jobs can have different sequence on different machines. A linear mathematical model for solving the non-permutation flowshop is developed to comply with all of the operational constraints commonly encountered in the industry, including dynamic machine availabilities, dynamic job releases, and the possibility of jobs skipping one or more machines, should their operational requirements deem that it was necessary. As the model is shown to be NP-hard, a metasearch heuristic, employing a newly developed concept known as the Tabu search with embedded progressive perturbation (TSEPP) is developed to solve, in particular, industry-size problems efficiently. The effectiveness and efficiency of the search algorithm are assessed by comparing the search algorithmic solutions with that of the optimal solutions obtained from CPLEX in solvable small problem instances.

4PL模式下基于时间资源调度的供应成本优化研究

订单时间是影响供应成本的主要因素,合理的进行时间资源调度更是供应成本优化的关键所在。现有的第四方物流(Fourth Party Logistics,4PL)路径优化研究只关注物流环节的时间和成本因素,没有与物流上一环节的整合。本文提出将4PL服务拓展到客户的生产环节,在供应商的生产时间窗约束下,构建模型得到生产时间与物流时间的最优组合方案使供应商供应成本最低。最后基于一个实例的分析,验证了该模型能有效帮助4PL为客户提供最优供应方案。     

行动导向教学法在《图形图像处理》课程中的应用

Reciprocity in Ranked Relationships: Does Social Structure Influence Social Reasoning?

Many economic and evolutionary theories have modeled cooperation as the evolutionary outcome of decisions made by autonomous, self-interested agents operating in a social vacuum. In this paper we consider the implications for cooperative interactions when prior social structures and corresponding social norms exist. In particular we investigate the influence of social rank/status on perceptions of fairness and tolerance of cheating. We review evidence from a series of experiments employing the Wason selection task (a test of conditional reasoning) and the ledger task (a decision making task) suggesting that people cued to adopt a perspective of high social rank are more tolerant of cheating and simultaneously believe that they have been more fairly treated (even when cheated) than people cued to adopt a perspective of low social rank. However, the evidence also suggests interesting cross-cultural differences in perceptions of fairness and tolerance of cheating in ranked relationships. This revised version was published online in August 2006 with corrections to the Cover Date.     

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.
