Centralized Bidding Procurement Process Optimization Of W Company

With the development of the construction industry in our country gradually mature in some companies belonging to the group of relatively large project procurement,group companies tend to adopt centralized bidding way,this is because,in the construction industry in the cost of various materials costs and machinery costs occupy an important share,is conducive to strengthening the centralized bidding the management of purchasing power concentrated on bidding adjustment,to reduce procurement costs,cost control is a long-term guarantee.Focus on purchasing rights to the enterprise group headquarters,the establishment of centralized bidding platform,with the scale of procurement advantages,through the group centralized procurement as much as possible to drive down the procurement costs,which is currently more common practice.But the bidding mode in its procurement scale at the same time,it also brings a series of problems,such as grading bidding to process lengthy,inefficient procurement bidding process is unreasonable,resulting in the delivery schedule can not meet the construction needs of the scene caused slowdown,bidding process is unreasonable cause of time delay has become a common problem of the purchasing mode.In order to effectively solve the construction unit of the scale of the procurement of the procurement schedule delay,it is necessary to start from the tender procurement business process,the tender procurement business process optimization.At present,the more common approach is to model the business process,in which Petri network is a more effective modeling method.Petri Net has been an important tool for the modeling of system business process,and it has a good ability of asynchronous concurrent process description and intuitive graphical interface.This paper summarizes the current domestic and international business process optimization and Petri net modeling of engineering material bidding process A group company as a typical case,analyzes the construction unit of the prevailing procurement business process is lengthy,progress is difficult to match with the construction progress of the procurement requirements of local emergency should be the situation of acute procurement difficulties.Through the use of modeling and simulation has higher ability of complex system structure of Petri net description method,the enterprise procurement process modeling,process by finding the bottleneck,according to business process optimization optimization rules.The feasibility and effectiveness of the optimization scheme are proved by comparing the variation of the flow period before and after the optimization.
