Many companies adopt concurrent engineering in their product-development projects in order to reduce time to market. Concurrent engineering requires careful management, since the uncertainty of transferred information leads to rework and renders a development process complex. Most of the existing studies on concurrent engineering have analyzed overlapping between two activities. The present study expanded the research scope by modeling the developmental process of the concurrent execution of multiple activities as the result of management decisions, the overlapping ratio, and the information transfer frequency. When multiple activities are overlapped, it is more difficult to model a development process, since the uncertainty of cascaded information has impacts on many activities. The quantitative model developed in the present study provides insights into the uncertainty of information and the product-development process. Based on the generalized process model for multiple-activity overlapping, the optimal decision to minimize project duration was considered. As a solution to the dilemma of the high computational burden of considering all feasible decision sets, this paper proposes a myopic heuristic. The project management heuristic proposed in this paper is intended to assist managers in the decision-making process, as well as reducing the intermediate deadlines in project main plan.

管理产品开发过程中多个活动的并发执行

许多公司在其产品开发项目中采用并行工程以缩短上市时间。并发工程需要仔细管理,因为传输信息的不确定性会导致返工并使开发过程变得复杂。大多数现有的并行工程研究都分析了两个活动之间的重叠。本研究通过对管理决策、重叠率和信息传递频率导致的多个活动并发执行的发展过程进行建模,扩大了研究范围。当多个活动重叠时,对开发过程建模更加困难,因为级联信息的不确定性会影响许多活动。本研究中开发的定量模型提供了对信息不确定性和产品开发过程的见解。基于多活动重叠的广义过程模型,考虑了最小化项目持续时间的最佳决策。为了解决考虑所有可行决策集的高计算负担的困境,本文提出了一种近视启发式。本文提出的项目管理启发式方法旨在帮助管理人员进行决策过程,并减少项目主计划中的中间期限。为了解决考虑所有可行决策集的高计算负担的困境,本文提出了一种近视启发式。本文提出的项目管理启发式方法旨在帮助管理人员进行决策过程,并减少项目主计划中的中间期限。为了解决考虑所有可行决策集的高计算负担的困境,本文提出了一种近视启发式。本文提出的项目管理启发式方法旨在帮助管理人员进行决策过程,并减少项目主计划中的中间期限。
