The Input-output Research About Electromechanical Equipments Renewal And Modernization Projects Of Expressway In Shandong

Because of the aging of expressway electromechanical equipment,The renewal of expressway Electromechanical Engineering is very important, Through the research of the electromechanical equipment renewal for shandong expressway company limited,We put forward some thoughts and methods of how to control input and increase output offers.In this article we put forward that the electrical Engineering renewal is divided into four stages:Early budget stage,Prophase planning stage, Planning implementation stage and later project management phase,In the early budget stages we analyse the investment,the benefits and the basic principle of equipment management by electromechanical equipment management system renewal,We propose through strengthening the budget process management, establishing equipment record and other ways to acquire larger profit.In prophase planning stage we propose the affecting factor according to the capital budget theory, Through analysing various factors on various projects we propose through controlling the process, reasonable budget means and other ways to control investment and ensure benefits. In the implementation of the plan stage we analyze the inputs and outputs,We propose the method to control bidding such as standard operation, rational selection of the bid assessment methods. In the later project management phase we put forward to formulate project plan, ensure project time, standard acceptance to control investment and achiev expected benefits.
