【摘要】：具有時(shí)間轉(zhuǎn)化約束項(xiàng)目網(wǎng)絡(luò)是對傳統(tǒng)網(wǎng)絡(luò)的創(chuàng)新,其考慮了時(shí)間轉(zhuǎn)換約束對項(xiàng)目網(wǎng)絡(luò)的影響。但是,在已有時(shí)間轉(zhuǎn)換約束項(xiàng)目網(wǎng)絡(luò)的研究過程中都是假設(shè)在整個(gè)工期內(nèi)工作效率是固定不變的,忽略了人為因素。而人在工作過程中具有學(xué)習(xí)效應(yīng),即隨著時(shí)間的推移人由對活動(dòng)的生疏逐漸到能夠熟練完成活動(dòng),在這個(gè)過程中工作效率也有了很大的提高。本文在前人研究的基礎(chǔ)上,考慮了人的行為因素對具有時(shí)間轉(zhuǎn)換約束網(wǎng)絡(luò)的影響,給出了在人的學(xué)習(xí)效應(yīng)和時(shí)間轉(zhuǎn)換約束雙重作用下的機(jī)動(dòng)時(shí)間的計(jì)算公式,進(jìn)而給出工序持續(xù)時(shí)間的計(jì)算公式,并在此基礎(chǔ)上建立了網(wǎng)絡(luò)關(guān)鍵線路的變化模型。最后,通過實(shí)例驗(yàn)證了該模型的有效性和合理性。
[Abstract]:The project network with time conversion constraints is an innovation to the traditional network, which takes into account the influence of time conversion constraints on the project network. However, in the research of the existing project network with time conversion constraints, it is assumed that the work efficiency is fixed and the artificial factors are ignored. In the process of work, people have the effect of learning, that is, with the passage of time, people gradually from the unfamiliar activities to be able to skillfully complete the activities, in the process of work efficiency has also been greatly improved. On the basis of previous studies, this paper considers the influence of human behavior factors on the network with time conversion constraints, and gives a formula for calculating maneuvering time under the dual action of human learning effect and time conversion constraint. Then the calculation formula of the working procedure duration is given, and the variation model of the network critical circuit is established on the basis of the formula. Finally, the validity and rationality of the model are verified by an example.
