  - - - Continuous systems
        
        They are those in which the facilities are standardized in terms of routes and flows by virtue of the inputs being homogeneous, consequently, a homogeneous set of processes and sequence of processes can be adopted.
      - Intermittent systems
        
        They are those in which institutions must be flexible enough to handle a wide variety of products and sizes.
      - Modular systems
        
        It makes it possible to have a large variety of relatively tall products and at the same time with a low variety of components.
      - Systems by projects
        
        The projects are characterized by high cost and by the difficulty of planning and administrative control.
    - - Secundarios
        
        These systems work as continuous and intermittent depending on the needs and market demand.
      - Tertiary
        
        They encompass the entire production or service system.
      - Primary
        
        These systems can operate as continuous or intermittent systems, depending on the demand in the market.
    - - Physical and Abstract
        
        Physical: They are those systems that exist physically.
        
        Abstracts: They are those that only exist in a conceptual way or in someone's mind.
      - Open and Closed
        
        Open: They are those where it is very difficult to predict their behavior.
        
        Closed systems: They are those that have objectives, inputs, products and relationships clearly determined so that the control, feedback and forecast can be established in a precise and objective way.
      - Natural and Elaborated
        
        The natural ones: They are those made by nature.
        
        The elaborated ones: By the man.
      - Technical and Civil or Social
        
        Technical systems: They are those that integrate and apply technology to achieve a goal.
        
        Los sistemas civiles o sociales: Tienen como finalidad la satisfacción de un objetivo social.
      - By Process
        
        By process: It is one that through a common process all products are made.
        
        By orders: It is one where each batch of different products follows a special process.
    - - Batch production system
        
        It is used by companies that produce a limited quantity of one type of product or service at a time.
        
        understands
        
        Physical arrangement: they are characterized by machines grouped in batteries of the same type.
        
        Production predictability: It must be constantly rethought and updated.
        
        Production plan: It is carried out in advance in relation to sales.
      - Continuous production system
        
        It is used by companies that produce a certain product without modifications for a long period, the pace of production is fast and operations run without interruptions.
        
        Steps
        
        Production plan: It is generally prepared for periods of one year, with monthly subdivisions. This system is used by manufacturers of paper, cellulose, automobiles, and household appliances.
        
        Physical arrangement: It is characterized by highly specialized machines and tools, arranged in linear and sequential formation.
      - Custom production system
        
        This is based on the order or order of one or more products or services.
        
        understands
        
        Physical arrangement: It focuses on the product.
        
        Production predictability: Each product requires a specific production plan.
        
        Production plan: List of raw materials, labor and production process.
  - - - In both cases, decisions must be made about capacity, location.
      - Both processes have external and internal suppliers, as well as external and internal customers.
      - In both cases, quality, productivity and customer response are of interest.
    - - manufactured goods are by-products that can be stored and services cannot.
      - Manufactured goods can be produced according to future demand and services cannot be produced in advance.
      - manufacturing companies: durable physical products and services: are perishable intangible products.
  - - - Other functions
        
        Operations function: Producer Department
        
        System: Steps that the transformation follows
        
        Decisions: In processes, capacities, inventories, workforce and quality
      - Relationship
        
        Purchases: acquisition of raw materials.
        
        Finance: acquisition and distribution of capital.
        
        Personnel (Human Resources): provides qualified labor.
        
        Accounting: production results are reflected in the Financial Statements.
        
        Marketing: responsible for creating demand
  - - - It is the relationship between the quantity of products obtained by a production system and the resources used to obtain said production.
    - - It is defined as the ability to generate the highest satisfaction from consumers by setting a price or the ability to offer a lower price by a certain quality.
    - - It is the ratio between the actual production obtained and the expected standard production.
    - - It is the degree to which the objectives are achieved, that is, the way in which a set of results are obtained reflects effectiveness, while the way in which resources are used to achieve them refers to efficiency.
