What is the standard capacity calculation formula?

According to the unit output of equipment * standard production time = standard capacity.

1, standard capacity: divide unit time by standard time to get standard capacity. For example, 1 hour (3600 seconds) /46 seconds =78, that is, the standard capacity of 14 "waist 1 hour is 78; For example, 8 hours /46 seconds = 620, that is, the standard capacity of 14 "waist disk for 8 hours is 620.

2. Production capacity refers to the number of products or raw materials that an enterprise can produce under the given organizational and technical conditions for all the fixed assets that it participates in the production during the planning period.

3. Calculation formula of production capacity: production capacity = unit working time/cycle time. Cycle time refers to the time interval of pulling out a unit product, which is equal to the bottleneck time of pulling. Unit working time refers to the attendance minus the waiting time generated by related activities.

4. Standard capacity = total time/(total number of workers * bottleneck time).

Supplementary information:

Capacity is an important issue for all enterprises and enterprises at all levels.

Production capacity refers to the maximum capacity that an operating unit can handle at full load. The work unit here can be a factory, a department, a machine or a worker.

When calculating the production capacity, we should grasp the following contents:

1. Determine the calculation unit of production capacity. Due to the extensive types of enterprises, the products and production processes of different enterprises are very different. Before calculating the production capacity, the unit of measurement of the production capacity of the enterprise must be determined.

(1) Input-output productivity is closely related to input-output. Different enterprises can choose input or output as the measurement unit of production capacity according to their own nature and other conditions. When an enterprise takes output as the unit of measurement, it needs to consider the number of products produced by the enterprise. If there is only one main product, it can be used as the unit of measurement; If a variety of products are produced, it is difficult to take the output of one product as the whole unit of measurement, so a representative product measurement method can be adopted. Select the product that represents the professional direction of the enterprise and has the largest output and man-hour quota as the representative product, and other products can be converted into representative products by conversion factors. The calculation formula of the conversion coefficient Ki is as follows: Ki=ti/to, where: the conversion coefficient of Ki-I product; Time quota of Ti-I products; To-indicates the time quota of the product. Sometimes the accuracy of calculating productivity by output is not high, which can not reflect productivity well, so input can be used as the unit of measurement, such as the total number of equipment and installed capacity.

(2) Some enterprises use a single fixed raw material to produce a variety of products. At this time, it is more appropriate to use the annual consumption of raw materials as the unit of measurement of production capacity. The production characteristics of such enterprises are often decomposition, that is, using a main raw material to decompose and manufacture a variety of products.

2. Determine the factors that affect the production capacity

(1) Product factors Product design has a great influence on production capacity. If similar products are produced, the operating system is more capable of producing such products than subsequent products. Generally speaking, the closer the output is, the more likely it is to standardize its production methods and materials, so as to achieve greater capacity. In addition, the specific product mix must also be considered, because different products have different yields.

(2) Personnel factors constitute the task of a job, and the training, skills and experience required by all kinds of personnel participating in activities to perform a task have an important impact on the potential and actual output. In addition, the motivation, absence and rolling of relevant personnel are also directly related to the production capacity.

(3) The design of production facilities, including the size of the factory building and the reserved expansion space, is also a key factor. Site factors, including transportation cost, distance from the market, labor supply, energy and expansion space, are also very important factors. Similarly, the layout of the work area also determines whether the production operation can be carried out smoothly.

(4) Process factors The product process design is an obvious factor that determines the production capacity, and whether the process design is reasonable or not affects the product quality. If the product quality fails to meet the standard, it will increase product inspection and rework, resulting in a decline in output.

(5) Operational factors An organization's scheduling problems, inventory decision-making, delayed delivery, acceptability of purchased raw materials and parts, quality inspection and process control are all caused by the contradiction of different equipment production capacity or work requirements, which all have an impact on effective production capacity.

(6) Other factors Product standards, especially minimum product quality standards, can limit managers' choice of increasing and using production capacity. For example, in order to meet the pollution standards of products and equipment, enterprises often reduce their effective production capacity.

3. Calculate the production capacity of batch processing enterprises. In this kind of enterprise, the organization of production department adopts the principle of process specialization, and the interval between product feeding and output is long and obvious. Their production capacity calculation is closely related to the division of workshops and teams according to the principle of process specialization.

(1) Calculate the productivity of a single device. Because the processed parts are not a single variety, the number can reach hundreds or thousands. All parts are different in shape and size, processing steps and processing time. At this time, the output can not be calculated, but can only be calculated by the effective processing time provided by the equipment, which is called machine time. The calculation formula is as follows: He = HO× η = HO (1-θ) = FO-S, where: HO- annual system working time; η —— Planned utilization rate of working hours of equipment system; θ —— planned repair downtime rate of equipment; S-planned downtime for equipment repair.

(2) Calculating the productivity of teams and groups The workshop team is the smallest production unit, and each team is equipped with a certain number of equipment with the same processing technology, but their performance and ability are not necessarily the same. Therefore, the calculation of team productivity starts with a single device, and then the productivity of these devices is integrated and calculated. If the processing technical parameters of all the equipment in the team are not much different, then the sum of the time of all the equipment is the production capacity of the team. If the technical parameters are quite different, it is necessary to separately count the machine hours of equipment with different parameters, and the key point is whether the processing capacity of some large workpieces can meet the production requirements.

(3) Determine the workshop capacity. Because the processing object of the team is parts, their productivity should be measured by machine hours. For the workshop, its production object is often the number of products or parts, so its production capacity should be measured by output. The conversion between working hours and output is relatively simple.

(4) Determining the production capacity of the factory The production capacity of the factory can be determined according to the capacity of the main production workshop, and the workshop with insufficient capacity can be solved by adjusting measures.

4. Calculate the production capacity of assembly line enterprises

(1) Calculate the production capacity of the assembly line. The production capacity of the assembly line depends on the production capacity of each process equipment, so it is calculated from a single equipment. The calculation formula is as follows: m sheets =He/ti, in which: m sheets-single equipment production capacity; He—— refers to the effective working time (hours) of a single equipment within the planned period (year); Ti—— Time quota (hours/piece) for processing a product on this equipment. If the process is undertaken by one equipment, the production capacity of a single equipment is the process capacity. When the process is undertaken by n sets of equipment, the production capacity of the process is m× n.

(2) Determine the production capacity of the workshop. If it is a manufacturing workshop, there are both parts processing assembly lines and parts assembly lines. At this time, its production capacity should be determined by the capacity of the assembly line. Even if the processing capacity of a single part is lower than that of the assembly line, it should be determined according to this principle. If it is a parts processing workshop, each part has a dedicated production line, and all parts are products of this enterprise, then the capacity of this workshop should depend on the capacity of the production line with the smallest capacity.

(3) Determination of enterprise's production capacity Because the processing objects and processes between workshops are very different, the performance of the selected equipment is very different, and the production capacity is also inconsistent. Therefore, the production capacity of basic production workshops is usually determined according to the leading production links. When the production capacity of the basic production workshop and the auxiliary production department is inconsistent, the enterprise shall determine the production capacity of the basic production workshop. Calculating production capacity is a necessary step to do a good job in capacity planning, and it is also a problem that enterprises must pay attention to. By calculating the production capacity of an enterprise, we can not only know our actual capacity, but also find bottlenecks and redundant links in the production process, providing basic information for scientific and reasonable planning of production capacity.
