This paper describes a simulation-based approach for developing a lean production system of multi-lean measures. Three lean measures are defined to characterize the leanness of the underlying production system: productivity, cycle time, and work-in-process inventory. An optimized setting to certain operational parameters is determined so that a best tradeoff of the three lean measures is reached. The problem formulation results in a multi-objective optimization problem with no closed-form definition of problem objective functions and constraints. The solution approach utilizes Discrete Event Simulation (DES) to deploy lean techniques and model lean measures under process variability and plant constraints and dynamics. A direct search method (i.e., Simulated Annealing (SA)) is used to search of problem domain. A model-based Value Mapping (VM) is used for combining the conflicting multi-lean measures and guiding the SA search for optima. The DES model is also used to develop a future state dynamic Value Stream Map (VSM) of the optimized production process. The approach is applied to an example production system where the capacity of material handling conveyors and the size of maintenance crew are optimized to develop a lean system in terms of three lean measures. Little’s formula is used to verify the simulation assessment of lean measures. Optimization results are also used to demonstrate the conflict among lean measures, the impact of process variability on lean measures, and the role of VM in reaching an efficient tradeoff of multi-lean measures. 相似文献

ABSTRACT This case study illustrates the application of Mega—adding measurable value for all stakeholders including society—as the central and ultimate focus for needs assessment. In this case, two needs assessment studies were conducted within a five‐year period (1999–2003) with the State of Ohio's Workforce Development (WD) program. An initial needs assessment based on Mega outcomes—high quality of life for Ohio taxpayers and public employees though the services they provide—was conducted in 1999, identifying shared strategic goals to focus management‐labor partnership initiatives. A Mega‐centered data collection matrix was used as the basis for discussions with stakeholders in order to determine the key areas of Ohio's Workforce Development to be included in the study. In 2003, a follow‐up needs assessment based on the same data collection matrix was designed to determine the improvements made since that time, the areas with the most critical performance gaps, demographic changes, and future trends affecting Workforce Development beneficiaries and stakeholders. 相似文献

文章从理论和实践层面对科研范式变革的主要内涵和重要影响进行综合性探讨。在理论层面上,从库恩及其代表作《科学革命的结构》入手,探讨“范式”概念的逻辑本质。在实践层面上,通过问卷调查和访谈等形式,调研、凝练出新时代科研范式变革的3个方面内涵：解决系统性复杂问题成为新时代科研范式变革主要驱动力,仿真模拟和数据科学可能成为推动科研范式变革的有效突破口,科研活动组织创新成为推动科研范式变革的基础。在此基础上,分析目前我国应对科研范式变革存在的问题,并提出相应的政策建议。 相似文献

Wave breaking plays an important role in sedi- ment transport and beach profile change. Breaking waves exhibit various patterns, principally depending on the incident wave steepness and the beach slope. The breaking patterns range from the relatively con- trolled spilling type to the violent and sudden plunging breaker type. The breaker patterns are classified into 3 or 4 categories. Some criteria for breaker pat- terns[1] are given in Tab. 1. Several wave decay models have been proposed to d… 相似文献

摘要：组合谈判策略的制定与选择是提升高技术虚拟企业个体谈判目标价值,保证联盟任务顺利执行的一条有效途径。本文全面分析个体Agent思维状态、外部环境信息、成员社会关系与行为模仿、议题空间特性等因素对联盟冲突决策的影响,提出高技术虚拟企业组合策略的执行方案与实施方法。结合个体Agent谈判策略的表现形式,建立回避、响应和折衷三种策略选择机制间的互动关系模型。促进了联盟多边谈判的网络资源、信息和知识的流动、共享和集成,并为群体谈判规划的确立以及谈判决策效力的发挥提供了有效支持。 相似文献
