【摘要】：網(wǎng)絡(luò)化產(chǎn)品協(xié)同設(shè)計(jì)是一種在分布式網(wǎng)絡(luò)環(huán)境下多學(xué)科、多群組協(xié)同的現(xiàn)代產(chǎn)品設(shè)計(jì)模式,它是指多學(xué)科群組人員針對(duì)一個(gè)復(fù)雜產(chǎn)品的設(shè)計(jì)目標(biāo)、相互協(xié)調(diào)、互相協(xié)作地完成一個(gè)產(chǎn)品設(shè)計(jì)的過(guò)程。協(xié)同設(shè)計(jì)的目的是為了提高產(chǎn)品的設(shè)計(jì)效率、縮短產(chǎn)品的設(shè)計(jì)周期、提升產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力。任務(wù)排序與任務(wù)調(diào)度問(wèn)題是網(wǎng)絡(luò)化產(chǎn)品協(xié)同設(shè)計(jì)研究的核心問(wèn)題之一,是產(chǎn)品實(shí)現(xiàn)協(xié)同設(shè)計(jì)的首要解決的問(wèn)題,因此,對(duì)協(xié)同設(shè)計(jì)中任務(wù)排序與任務(wù)調(diào)度策略的研究具有十分重要的意義。本文在分析了網(wǎng)絡(luò)化產(chǎn)品協(xié)同設(shè)計(jì)任務(wù)排序與調(diào)度國(guó)內(nèi)外研究現(xiàn)狀和所使用的關(guān)鍵技術(shù)的基礎(chǔ)上,針對(duì)產(chǎn)品設(shè)計(jì)任務(wù)拆分后子任務(wù)之間的復(fù)雜關(guān)系,本文提出一種基于模糊矩陣方法構(gòu)建子任務(wù)模型的協(xié)同任務(wù)的調(diào)度策略。首先,利用任務(wù)間的關(guān)聯(lián)程度建立產(chǎn)品設(shè)計(jì)的任務(wù)集,并引入重要度參數(shù),以重要度為參考對(duì)任務(wù)集內(nèi)全部子任務(wù)進(jìn)行排序;其次,分析任務(wù)集之間的耦合度和并行度,確定任務(wù)執(zhí)行時(shí)間的分配策略,并利用建立好的排序規(guī)則和任務(wù)狀態(tài)模型建立動(dòng)態(tài)的調(diào)度策略。最后,實(shí)驗(yàn)驗(yàn)證了所用算法和策略的可行性和有效性。本文的主要工作如下:(1)協(xié)同設(shè)計(jì)過(guò)程的任務(wù)分解和排序問(wèn)題研究。針對(duì)任務(wù)的耦合度、重要度等多個(gè)特征,建立一種協(xié)同設(shè)計(jì)的任務(wù)排序方法,以及任務(wù)的時(shí)間分配策略。(2)協(xié)同設(shè)計(jì)的并行與串行調(diào)度問(wèn)題研究。針對(duì)協(xié)同設(shè)計(jì)任務(wù)執(zhí)行的動(dòng)態(tài)不確定性問(wèn)題,給出了任務(wù)集之間的并行調(diào)度策略和任務(wù)集內(nèi)部子任務(wù)之間的串行調(diào)度策略。(3)設(shè)計(jì)開發(fā)了一個(gè)網(wǎng)絡(luò)化協(xié)同設(shè)計(jì)任務(wù)排序與調(diào)度管理原型系統(tǒng),驗(yàn)證所提方法的有效性。網(wǎng)絡(luò)化產(chǎn)品協(xié)同設(shè)計(jì)任務(wù)排序與調(diào)度問(wèn)題的研究,為網(wǎng)絡(luò)化協(xié)同創(chuàng)新環(huán)境下,產(chǎn)品設(shè)計(jì)的過(guò)程管理提供了一種有效的方法。
[Abstract]:Networked product collaborative design is a kind of modern product design pattern of multi-disciplinary and multi-group collaboration under distributed network environment. It refers to the coordination of multidisciplinary group personnel for a complex product design goal. Work together to complete a product design process. The purpose of collaborative design is to improve the design efficiency, shorten the design cycle and enhance the market competitiveness. Task ranking and task scheduling is one of the core problems in networked product collaborative design and the most important problem to be solved in product collaborative design. It is of great significance to study task scheduling and task scheduling strategy in collaborative design. Based on the analysis of the status quo and the key technologies used in the task scheduling and scheduling of networked product collaborative design, this paper aims at the complex relationship between the sub-tasks after the separation of product design tasks. In this paper, a scheduling strategy for collaborative tasks based on fuzzy matrix method is proposed. Firstly, the task set of product design is established by using the degree of correlation between tasks, and the importance parameter is introduced to sort all the sub-tasks in the task set with the importance degree as the reference. Secondly, the coupling degree and the degree of parallelism among the task sets are analyzed. The assignment strategy of task execution time is determined, and the dynamic scheduling strategy is established by using the established collation rules and the task state model. Finally, the feasibility and effectiveness of the proposed algorithm and strategy are verified by experiments. The main work of this paper is as follows: 1) Task decomposition and scheduling in collaborative design process. According to the characteristics of task coupling and importance, a task scheduling method for collaborative design is proposed, and the parallel and serial scheduling problems of task scheduling are studied. For the dynamic uncertainty of collaborative design task execution, The parallel scheduling strategy between task sets and the serial scheduling strategy between subtasks in task set are given. A prototype system of task scheduling and scheduling management for networked collaborative design is designed and developed to verify the effectiveness of the proposed method. The research on task ordering and scheduling of networked collaborative product design provides an effective method for process management of product design in networked collaborative innovation environment.
