Production and Operation Management - deals with the creation of goods and services through the application of the business concept. They are also vital in both service and manufacturing firms.
Production and Operation Management - has a primary objective, which is to employ the company’s resources to produce goods and services fit for the market.
production system - of an organization is that part, which produces products of an organization.
production system - It is that activity whereby resources, flowing within a defined system, are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management.
The production system has the following characteristics:
A) ORAGANIZED ACTIVITY
B) objective
C) various inputs to useful outputs
D) it does not operate in isolation
E) feedback
Classification of Production Systems
continuous production
mass production
batch production
job-shop production
production system
A) continuous production
B) mass production
C) batch production
D) job-shop production
job-shop Production - are characterized by manufacturing of one or few quantity of products designed and produced as per the specification of customers within prefixed time and cost.
Job-shop Production - The distinguishing feature of this is low volume and high variety of products.
Job-shop Production - compromises of general purpose machines arranged into different departments.
Job-shop Production - Each job demands unique technological requirements, demands processing on machines in a certain sequence.
Batch Production is defined by American Production and Inventory Control Society
batch production - form of manufacturing in which the job passes through the functional departments in lots or batches and each lot may have a different routing.
batch production - It is characterized by the manufacture of limited number of products produced at regular intervals and stocked awaiting sales.
mass production - Manufacture of discrete parts or assemblies using a continuous process
mass production - This production is justified by very large volume or production. The machines are arranged in a line or product layout.
mass production - Product and process standardization exists and all outputs follow the same path.
continuous production - Production facilities are arranged as per the sequence of production operations from the first operations to the finished product.
continuous production - The items are made to flow through the sequence of operations through material handling devices such as conveyors, transfer devices, etc.
Production function - is that part of an organization, which is concerned with the transformation of a range of inputs into the required outputs (products) having the requisite quality level.
production is defined as:
A) step by step
B) value addition process
C) goods and services
examples of production?
manufacturing custom made product
manufacturing standardized product
Manufacturing Custom-Made Products -boilers with a specific capacity, constructing flats, some structural fabrication works for selected customers, etc.
Manufacturing Standardized Products - car, bus, motor cycle, radio, television etc.
operation - is defined in terms of the mission it serves for the organization, technology it employs and the human and managerial processes it involves.
Operations - in an organization can be categorized into manufacturing operations and service operations.
Operating system - converts inputs in order to provide outputs which are required by a customer.
operating system - It converts physical resources into outputs, the function of which is to satisfy customer wants i.e., to provide some utility for the customer.
Operating system - function of an organization is the part of organization that produces the organization’s physical goods and services.
Operating system - is a configuration of resources combined for the provision of goods and services.
Manufacturing operations and service operations are often different in terms of what is done but quite similar in terms of how it is done.
difference between manufacturing operations and service operations
degree of customer contact
labor content of jobs
measurement of productivity
quality assurance
inventory
wages
ability to patent
Degree of customer contact - Many services involve a high degree of customer contact, although services such as Internet providers, utilities, and mail service do not.
When there is a high degree of contact, the interaction between server and customer becomes a “moment of truth” that will be judged by the customer every time the service occurs.
Labor content of jobs - Services often have a higher degree of labor content than manufacturing jobs do, although automated services are an exception.
manufacturing operations - often have a greater ability to control the variability of inputs, which leads to more-uniform job requirements.
Measurement of productivity can be more difficult for service jobs due largely to the high variations of inputs.
Quality assurance - is usually more challenging for services due to the higher variation in input, and because delivery and consumption occur at the same time.
services - tend to involve less use of inventory than manufacturing operations, so the costs of having inventory on hand are lower than they are for manufacturing
