Common planning unit

The product planning unit is based on the product as a calculation unit for allocating production tasks when preparing a production operation plan.

Its characteristic is that when the operation plan is issued, only the product name,

The part planning unit is a unit of calculation for allocating production tasks. When preparing a production operation plan, the production quantity and the input production time of each component are specified according to the order of assembly. Each production workshop independently arranges the input and output quantity and time according to the complete parts list of a certain component and the corresponding production cycle.

The advantage of such a planning unit is that it can fully ensure the completeness of the production of parts, reduce the occupation of work in process, and have certain flexibility in the workshop. However, the workload of preparing the operation plan is increased, and there is still a backlog of parts with short production cycles in the set of parts. Since the same parts in different parts cannot be concentrated in batch production, the production efficiency is reduced.

The part unit planning unit is to divide parts with similar structures, processes, and production organization forms into parts groups as a calculation unit for assigning tasks. When you release a production task, you do not need to list the part names, but only release by part group. The production unit organizes production according to the detailed list of parts and components.

The advantage of this kind of planning unit is that it can organize the batch production of similar parts, expand the batch and improve the efficiency, and can reduce the waiting time for parking the parts, which has good economic effect. Disadvantages are the complex grouping of parts and the heavy planning effort.

The part planning unit is a calculation unit that can release production tasks for each part in the product. When preparing the production operation plan, specify the input and output time and quantity of each part. The advantage of this type of planning unit is that it can organize production according to the different characteristics of parts, which is conducive to connecting parts between production sections, greatly reducing the waiting time for part parking and shortening the production cycle. At the same time, the work-in-progress occupancy in the production process is small, which is conducive to saving working capital and good economic results. However, the disadvantage is that the planning workload is very large. Due to the large number of parts, it is difficult to guarantee the production of complete sets of products.

The selection of the product's planning unit is generally based on the characteristics of the type of production, which is conducive to simplifying the planning of production operations, giving play to the initiative of each production link, and ensuring the principle of ensuring that the production tasks are completed on schedule and in sets. The above four types of planning orders are often used in combination. An enterprise can use several planning units at the same time, different products use different planning units, and the same product can use different planning units in different production links.
