System - A collection of entities (objects, people, …) interrelated to each other forming a complex
Classification
· Natural systems – Obey and behave according to the laws of nature
· Man-made systems – designed and operated by people
· Dynamic vs Static
· Adaptive vs Non adaptive
· Continuous vs Discrete
· Deterministic vs Stochastic (probabilistic)
· Stable vs Unstable
Components of a system
· Input
· Process
· Output
Types of Process (Operations)
· Physical
· Exchange
· Locational
· Physiological
· Informational
· Etc
Values created by systems
· Form
· Place
· Time
· Possession
Forces affecting systems
· Technology
· Society
· Economy
· Politics
· Competition
What is operations – is the management of productive systems
What do operations managers do?
· Quality management
· Capacity management
· Capacity management
· Inventory management
· Product/process design
· Forecasting
· Etc
Strategic Plan – by top management
· Set goals
· Set priorities to compete – order winner vs order qualifier
· Price
· Quality
· Flexibility
· On-time delivery
· Customer service
Productivity = output(s) / input(s)
Reasons for delaying the progress
· Lack of direction
· Lack of support
· Too much work
· Inefficient process
· Not enough equipment or supplies
· Low pay
· No chance to advance
Range of activities fall under product/service design
· Translate customers wants and needs into product/service requirement
· Refine existing product/service
· Develop new product/service
· Formulate quality goals
· Formulate cost targets
· Construct and test prototype
· Document specification
Reasons for product/service design or redesign
· Economic
· Social & demographic
· Political, liability, legal
· Technology
· competition
· costs
· availability
· labor
· materials
· resources
Objectives of design
· customer satisfaction – wants & needs
· quality, volume, ease of production, profit, cost, operations (called design for operations)
Phases of product design
· Idea generation – research, technology, reverse engineering
· Feasibility study – finance, operations, marketing
· Product specification
· Process specification
· Prototype development
· Design review
· Market test
· Product introduction
· Follow-up evaluation
Capacity – the capability of a system to produce a quantity of output in a given period or provide service.
· Capacity levels:
· Design
· Effective
· Actual
Utilization = actual / design
Efficiency = actual /effective
Too much capacity – unused equipment, higher inventory, low profit
Too little – lost sales
Capacity bottleneck – theory of constraint
Capacity planning – to determine the appropriate level of capacity to meet demand
Questions to ask:
· New facility
· Modify or expand existing facility
· Close existing facility
· Single site or multiple sites
· One large facility or several small facilities
· Location
· Close to customers
· Close to suppliers
· When to build
· Match demand
· Lead demand
Managing capacity and demand (short-term)
· Part-time help
· Share capacity
· Use of off peak demand
· Do it faster
· Avoid chatting
· Appointment
· Partition demand
· Back order
· Complementary service
· Import customers
· Customer participation
· Change schedules
· Cross training
Initiating capacity planning
· Increase/decrease demand
· Changing technology
· Changing environment
· Spotting opportunities
Steps in the capacity planning process
· Audit and evaluate the existing capacity
· Forecast capacity requirement
· Define capacity alternatives
· Do financial analyses
· Assess key qualitative issues
· Select an alternative
· Implement the alternative
· Audit and review the actual results
