As shown in fig. 1 to 6, the present invention relates to a process assembly construction method, and in particular, to a production method of a PBOM-based process assembly for complex scenarios. The method is characterized in that based on PBOM, the structural relationship is reconstructed by taking a process flow as a main line, the influence of each material of the EBOM on task segmentation, logistics turnover, warehouse management, planning scheduling and financial accounting is inspected from the process angle, the optimal solution of the process material is formed by reasonably reconstructing the material, basic data support is provided for the back-end MBOM, and the method is an important component in an EBOM-PBOM-MBOM-QBOM data chain. The process assembly construction method provided by the invention can be suitable for PBOM reconstruction with the characteristics, and can be used for realizing production organization flow optimization, reducing workload, shortening planning period, saving cost, concentrating production resources, flexibly producing and other manufacturing demands.
In order to solve the technical problems in the background technology, the invention provides a production method based on a PBOM process assembly for complex scenes, and particularly aims at optimizing 5 production organization scenes and combinations thereof based on process material requirements, manufacturing task diversion, unitization management, ready period management and maturity for process assembly construction.
The specific method comprises the following steps:
scene one: based on process material requirements;
the process assembly is constructed based on the process material requirements, the materials required by the product manufacture are combined according to the process, and the process assembly has the following advantages:
1) And starting in advance. The material alignment sleeve required by the previous working procedure can be started without waiting for all the material alignment sleeves.
2) Avoiding invalid streams. The materials required by the following working procedures do not need to be circulated along with the working procedures at the beginning, so that the resource waste is caused.
The construction method comprises the following steps: step A1 process attribute definition, step A2 process planning, step A3 process material planning and step A4 process assembly construction.
The process attribute definition in the step A1 is to distinguish all materials in the EBOM according to the types of products, and the major class to the minor class can be respectively defined as a process attribute 1, a process attribute 2, a process attribute … … and a process attribute n. The broad process attribute definition also includes a process route definition that determines the general process flow of the material.
The step A2 process planning is to program a process procedure rule card of the component/whole according to the defined process attributes and process routes by a craftsman, and to program a detailed process flow of the component/whole product manufacturing.
And the step A3 of process material planning is to arrange materials required by each process according to the manufacturing process of the parts/whole parts by a craftsman and plan the materials according to the process.
The step A4 process assembly construction is based on EBOM, PBOM is reconstructed based on process material requirements, and the process assembly is constructed according to the process.
Scene II: shunting based on manufacturing tasks;
the process assembly is constructed based on the split flow of manufacturing tasks, and the materials required by the manufacturing of the product are combined according to sources, so that the process assembly has the following advantages:
1) The manufacturing task is split. The ERP system logic can only generate one manufacturing task for the same batch of material numbers at a time, and when the product relates to a plurality of manufacturing responsibility subjects, the manufacturing task can not be split. The materials with the same source form a process assembly, so that the difficult problem of shunting of manufacturing tasks is solved.
2) Management improvement. Materials with the same source are manufactured, purchased or outsourced uniformly, so that the management workload is reduced.
The construction method comprises the following steps: step B1 manufacturing type definition, step B2 manufacturing responsibility entity definition, step B3 process assembly construction.
The manufacturing type definition in the step B1 is to distinguish all materials in the EBOM according to the product manufacturing or purchasing mode, and the manufacturing type definition is mainly divided into three main types of self-made parts, outsourcing parts and outsourcing parts. The self-made part is a material manufactured by the inside of an enterprise, the outsourcing part is a material obtained by the enterprise in an external purchasing mode, and the outsourcing part is a material obtained by the enterprise in a manufacturing outsourcing mode.
The main definition of the manufacturing responsibility in the step B2 is to define the manufacturing party according to the source of the materials. The self-made parts can be subdivided into machining self-made parts, microwave self-made parts, extension self-made parts, complete machine self-made parts and the like according to functions, different self-made parts correspond to different production workshops, and each production workshop is a main body of manufacturing responsibility of the self-made parts. The outsourcing piece corresponds to different suppliers according to the supply chain, and each supplier is the main body of the manufacturing responsibility of the outsourcing piece. The outsourcing piece is based on manufacturing outsourcing management and corresponds to different outsourcing providers, and each outsourcing provider is the main body of manufacturing responsibility of the outsourcing piece.
The construction of the process assembly in the step B3 is to distinguish materials according to different manufacturing responsibility bodies and respectively combine the materials. The machine processing assembly, the microwave process assembly, the extension process assembly, the complete machine process assembly and the like can be constructed according to different production workshops from the finished piece. The outsourcing component may build a vendor a process assembly, a vendor B process assembly, etc. according to different vendors. The outsource agreement may build an outsource provider a process kit, an outsource provider B process kit, etc. according to different outsource providers.
Scene III: group-based management;
based on unitized management, a process assembly is constructed, materials required by product manufacture are combined according to types, and the method has the following advantages:
1) The workload is reduced. The number of orders is reduced from N to 1 by combining N materials of the same type, so that the workload of warehouse-in and warehouse-out management, batching, planning management and control and the like is reduced.
The construction method comprises the following steps: step C1 process attribute definition, step C2 grouping requirement identification, and step C3 process assembly construction.
The process attribute definition in the step C1 is to distinguish all materials in the EBOM according to the types of products, and the materials from major class to minor class can be respectively defined as process attribute 1, process attribute 2, … … and process attribute n until the manufacturing modes of the materials in the same minor class are basically consistent after classification.
And C2, grouping requirement identification is to count the quantity of materials in the same subclass, and determine which materials are subjected to grouping management and which materials are subjected to fine management according to management requirements.
And C3, constructing the process assembly, namely constructing the process assembly for the materials of the same subclass according to the grouping requirement, and uniformly managing the process assembly. For example, a plurality of orders are compressed into 1 order by a plurality of cable construction process assemblies of the same type, the warehousing and the ex-warehouse are only required once, the batching is only required 1 time, the planning management is only required to aim at one order, and the workload is greatly reduced.
Scene four: managing based on the ready period;
the process assembly is constructed based on ready cycle management, which combines materials required by product manufacture according to the ready cycle, and has the following advantages:
1) Shortening the planning period. The materials with long ready period are put into production in advance, resources are concentrated, and the planning period can be effectively shortened.
2) Releasing the manufacturing resources. The material with short ready period is put into production in a delayed mode, and manufacturing resources are not occupied in the early stage.
The construction method comprises the following steps: step D1 material ready cycle evaluation, step D2 ready cycle segment partitioning, step D3 process assembly construction.
And D1, evaluating the material ready period according to aspects of a supply chain, a manufacturing or purchasing mode, material characteristics, unit productivity and the like, and respectively evaluating the manufacturing or purchasing period to form a material ready period schedule.
The step D2 of ready period segment division is to segment the material ready period, for example, short ready period materials within 1 month, medium ready period materials within 1-3 months and long ready period materials exceeding 3 months, by comprehensively considering production resources and planning management and control requirements.
The step D3 process kit construction is based on a pull-type schedule, pushing back the start time of each material manufacture or purchase from the start time of assembly of the product. The materials of the same ready cycle segment are combined to form a ready cycle process assembly. The process assembly with long ready period is put into production in advance, and the process assembly with short ready period is put into production in a delayed manner, so that the optimization of the planning period and the manufacturing resources is realized.
Scene five: management based on manufacturing maturity;
the process assembly is constructed based on manufacturing maturity management, which combines materials required by product manufacturing according to manufacturing maturity requirements, and has the following advantages:
1) Optimizing the management mode. In the initial production of the product, the manufacturing process is more conservative due to the immaturity of technology, management, supply chain and the like. When the product is subjected to pattern, initial pattern, small batch production and batch production, the manufacturing process gradually tends to be efficient and low in cost.
2) The manufacturing modes are diversified. After the manufacturing maturity is improved, the manufacturing modes of the same materials are more diversified, and more choices exist.
The construction method comprises the following steps: step E1 manufacturing maturity evaluation, step E2 maturity promotion optimization, and step E3 process assembly construction.
The step E1 manufacturing maturity evaluation is to evaluate the manufacturing maturity of the product according to GJB 8345-2015 equipment manufacturing maturity grade classification and definition, comprehensively considering ten aspects of industrial foundation and manufacturing technology system, design, technical maturity, process, materials, equipment facilities, manufacturing personnel, manufacturing management, quality management and cost management, and classifying the manufacturing maturity into ten grades.
The step E2 maturity promotion optimization is management optimization which can be performed when one main evaluation dimension has maturity level promotion, and comprises batch purchasing, SOP assembly, manufacturing outsourcing, design optimization, process optimization and the like.
And E3, constructing the process assembly according to the management optimization, and respectively combining materials to construct the corresponding maturity process assembly. The maturity process kit allows for flexible options to be implemented using different manufacturing modes.
Scene six: the above five scenarios are combined with each other.
The construction scenarios of the five process packages described above can be combined with each other as needed to meet more production organization requirements.
For example, scenario one (based on process material demand) and scenario two (based on manufacturing task split), materials required for the same process are again separated into self-made process assemblies (including machining process assemblies, microwave process assemblies, extension process assemblies, complete machine process assemblies, etc.), outsourcing process assemblies (vendor a process assemblies, vendor B process assemblies, etc.), outsourcing process assemblies (outsourcing vendor a process assemblies, outsourcing vendor B process assemblies, etc.) according to manufacturing tasks.
For example, scene one (based on process material demand) and scene four (based on ready cycle management) are combined, and materials required for the same process are divided into a short ready cycle process assembly, a medium ready cycle process assembly and a long ready cycle process assembly according to the material ready cycle.
The construction requirements of the prior art assembly are mainly focused on establishing an assembly hierarchical relationship, and the application range is narrow. In order to solve the problems, the invention provides a production method of a PBOM-based process assembly for complex scenes, which has the following advantages: 1) The method is suitable for various production organization scenes, and fully exerts the advantages of PBOM on EBOM secondary reconstruction; 2) The method forms a descriptive rule which can be applied to the automatic realization of process design software; 3) The reasonable application of the process assembly can optimize the production organization management flow, reduce the workload, shorten the planning period, save the cost, concentrate the production resources and assist the lean production.
The invention has the beneficial effects that:
