Collaborative project management in the hottest ne

Collaborative project management in networked manufacturing environment introduction since the late 20th century, the globalization of market and competition has become an important development trend. On the one hand, global market competition and customized non-standard products require enterprises to respond quickly to market opportunities and effectively provide high-quality, low-cost products or services. It is difficult for a single enterprise to meet this requirement, which requires enterprises to quickly form an alliance for market opportunities, give full play to their core competence advantages, and jointly realize market opportunities. On the other hand, advanced information technology and communication technology (ICT) make it possible for enterprises to cooperate in a distributed mode. Under the influence of these two main aspects, networked manufacturing with the basic characteristics of digitalization, flexibility and agility has been formed

the so-called networked manufacturing refers to the flexible and rapid organization of social manufacturing resources by using the information highway marked by Internet in the face of market opportunities and the needs of a certain market, and the rapid combination of the existing production equipment resources, intellectual resources and various core capabilities scattered in different regions into a kind of equipment that has no walls, transcends spatial constraints, and is connected by electronic means according to the principle of complementary resource advantages Unified command of the business entity network alliance enterprises, which are closely related to China's extruder products and strategic new industries, in order to quickly launch high-quality and low-cost new products. The manufacturing of complex products is carried out by forming a temporary enterprise alliance according to a specific market demand. Therefore, the project management mode is usually used for production management. Networked manufacturing brings new characteristics to project management, which makes collaborative project management in networked manufacturing environment become another hotspot of current research

2 characteristics of collaborative project management in networked manufacturing environment

collaborative project management in networked manufacturing environment has the following characteristics:

(1) goal oriented. The goal is to realize the opportunity and the final state of the project

(2) timeliness. The project has a life cycle. Therefore, the enterprise alliance based on the project has timeliness. It begins with the emergence of the project and ends with the completion of the project

(3) distribution. The enterprises undertaking the project are temporary enterprise alliances, so they are dispersed in geographical location. At the same time, because different enterprises undertake different sub projects or tasks of the project, they also have distribution characteristics in time

(4) close cooperation and a high degree of autonomy. 6. For new materials related to the culture and art industry, due to the time and logical dependency between the sub projects (or tasks) of the project, it is required that the partner enterprises must cooperate closely to complete the overall goal of the project. However, each enterprise in the alliance is an independent economic entity, and they are equal partners without forming a hierarchical control structure

3 architecture and key technologies of collaborative project management

3.1 architecture

determine its architecture according to the characteristics of collaborative project management in networked manufacturing environment, as shown in Figure 1

as can be seen from Figure 1, project schedule management and project cost management are the two main lines of collaborative project management

3.2 key technology

3.2.1 collaborative project planning and control

from the networking system, the shrinkage along the vertical material flow direction is large; On the contrary, it can be seen from the collaborative project management architecture in the manufacturing environment that the collaborative project plan is a multi-level and multi-layer network plan, and its overall experimental processing process is carried out separately, as shown in Figure 2

(1) according to the requirements of the contract and the initial decomposition of WBS (work breakdown structure), the sub projects and tasks of the project should be allocated within the enterprise alliance, and the results should be negotiated with the allied enterprises

(2) according to the task allocation of the project in the alliance and the project delivery date, the project network plan and production scheduling should be carried out, and the key resources should be balanced. If there is no conflict in resources, the alliance project benchmark plan should be generated and negotiated, otherwise the task allocation adjustment should be carried out

(3) under the constraint of the alliance project benchmark plan, the alliance enterprise should carry out the formulation, project scheduling and monitoring of the implementation plan within the enterprise. The leader enterprise is responsible for the collection and analysis of production data, the handling of abnormal conditions and the change control of plans

3.2.2 cost planning and control of collaborative projects

cost planning and control of collaborative projects are based on the negotiation mechanism between enterprises. In cost planning and control, the funds allocated to other allied enterprises are the costs of the allied enterprise in this sub project and task. The cost planning and control of sub projects and tasks are carried out within the scope of a single enterprise. Therefore, the key to collaborative project cost planning and control is project cost budget and allocation. For different enterprise alliance formation methods, there are the following two cost budgeting and allocation methods

(1) top down cost budget and allocation method. In collaborative projects, when competing for project contracts, multiple enterprises form an alliance to jointly obtain the project. In this kind of collaborative projects, the budget and allocation of costs are top-down decomposition of project costs by the alliance owner enterprise according to the project WBS, and the costs are allocated to each task of the project, so as to form a CBS (cost breakdown structure). According to the undertaking enterprise of each task, the enterprise decides to pay the fund to the corresponding partner enterprise, and negotiates with the alliance enterprise, that is, the fund paid to the partner enterprise is the alliance
