Description
Technical Field
The invention relates to the technical field of building construction scheduling, in particular to a method and a system for performing construction scheduling based on a building engineering model.
Background
At present, the building construction scheduling is manually managed, various materials required by engineering construction are purchased in advance according to the construction progress, but in practice, temporary change of a demand plan, temporary material allocation, urgent material standing and the like, and urgent time are often difficult to achieve reasonable and economic purchasing according to a program. The material is not strictly distributed according to the material consumption quota, and materials are only timely supplied according to engineering requirements in construction; the use process of the materials is difficult to monitor, and serious waste phenomenon exists in the actual use of the materials: the method is lack of effective and timely waste material recovery, only the last waste material recovery work is performed after the construction period is completed, and the loss of leftover materials is serious. Summarizing, mainly the following problems are included:
the material is collected by people, but the capability and quality of material management staff are not high. In the building industry of China, the phenomenon that recruitment of project management talents is not paid attention to is common, most building enterprises allocate common staff to monitor building materials at will from other departments in the unit in order to save cost, and special professional talents with management capability are not used for managing the building materials or management is carried out by using daily management means. These management staff, whether they have a gap from the requirements of modern engineering material management in terms of management ability or professional literacy, are mainly represented by: low professional knowledge level, insufficient practical experience, insufficient self-restraint and the like. Even if some personnel have high management capability and rich actual combat experience, the lack of professional management knowledge is not in line with the requirements of engineering building material management. The management mode is easy to cause the phenomenon of disordered enterprise management, is unfavorable for the cost control of building materials, is unfavorable for the scientific management of the building materials, and greatly influences the smooth development of building engineering.
The purchasing procedure of the building engineering materials is disordered: in practical engineering projects, effectively controlling building material funds has a direct impact on the overall cost of construction engineering. At present, most building enterprises lack cost consciousness in the process of purchasing building materials, blind purchasing is not provided with detailed purchasing schemes, and detailed budget is not provided for purchasing cost. Before purchasing, the market is not known, and the prices of building materials on the market are not mastered in detail, so that the prices of the materials are maliciously increased by partial suppliers, and the prices are important factors for increasing purchasing cost. Therefore, before purchasing building materials, the market price is thoroughly mastered, a detailed purchasing plan is formulated, so that purchasing cost funds can be effectively controlled, the investment of construction engineering cost and total cost is more effectively reduced, and scientific management of engineering construction enterprises is realized.
