Description

Technical Field

[0001] The present invention relates to the technical field of resource allocation, and in particular to a construction site resource integration and allocation system. Background Art

[0002] The field of resource allocation technology focuses on how to effectively allocate and manage limited resources to achieve specific goals and maximize resource utilization efficiency. In many industries, especially in construction, manufacturing, software development and service provision, resource allocation is a key operational activity. This technology field uses various computational methods and algorithms, such as linear programming, network flow analysis, queuing theory and simulation models, to optimize the allocation of resources. Resources can include time, manpower, money, equipment and information. Effective resource allocation can not only improve efficiency, but also reduce waste and cost, and increase project success rate.

[0003] Among them, the construction site resource integration and allocation system refers to a system used to manage various resources in a construction project. Its main purpose is to ensure that the resources in the project, such as manpower, machinery and equipment, materials and funds, are optimally configured and utilized. This type of system helps project managers allocate the right resources to the right place at the right time through accurate prediction and planning of resource requirements, thereby improving the efficiency of the construction site, reducing resource waste, speeding up the project progress, and possibly reducing overall costs. By integrating and allocating resources, these systems support complex decision-making and make construction projects more systematic and predictable.

[0004] Existing technologies mainly use static models for resource allocation, which lack the ability to respond to dynamic conditions on the construction site. This model is difficult to adapt to the immediate impact of emergencies on resource demand, resulting in resources being overused or idle in the short term. In addition, existing methods fail to effectively integrate historical data for resource demand forecasting and often rely on subjective judgment, resulting in uneven resource allocation and inefficiency. This limitation of lacking a dynamic adjustment mechanism increases project costs, increases risks and uncertainties, and affects the overall efficiency and cost control of the project.
