Capacity, Layout, and Inventory Management Techniques

Capacity Management

  • Capacity: The maximum output a system can achieve. Understanding capacity helps align resources with demand.

    • Types of Capacity

      • Design Capacity: Theoretical maximum output.

      • Effective Capacity: Practical maximum output considering constraints.

      • Actual Capacity: Realized output under actual operating conditions.

    • Capacity Measures

      • Input Measures: Labor hours, machine hours.

      • Output Measures: Units produced, services delivered.

  • Capacity Utilization

    • Indicates how efficiently capacity is being

Time Series Analysis, Forecasting & Operations Management Concepts

Time Series Components

A time series is a set of values of a variable measured at successive points in time.

Key Components

  • Trend: The gradual increase or decrease of a time series over a longer period.
  • Seasonality: Regular patterns of variability within certain time periods, such as a year, week, etc.
  • Cycle: Any regular pattern above and below the trend line lasting more than one year.
  • Random Variations: Fluctuations caused by chance events and/or unusual situations.

Mastering the Maturation Period: Inventory & Sales Cycle

Understanding the Maturation Period

The maturation period of a company is the time it takes from purchasing raw materials to converting them into sales, encompassing warehousing, manufacturing, and sales processes. A longer maturation period necessitates more working capital.

Averaging the Maturation Period

Companies experience various cycles, which can be categorized as:

  • Long-term cycles: These cycles involve fixed assets and span from acquisition to depreciation or renewal.
  • Short-term cycles: These

Statistical Analysis: ANOVA, Experiments, and Variable Types

Statistical Analysis Definitions and Assumptions

Observational Study: Data is collected without any attempt to manipulate or influence the outcome.

Planned Experiment: Some manipulation is attempted in order to see if the outcome is related to the controlled factor.

Independent Variable: The variable that is manipulated.

Dependent Variable: Variable that is not manipulated but is affected by the independent variable.

Stratification: Units in the sampling frame are first divided into groups.

Simple Treatment:

Key Probability Definitions and Rules

Sample Space Definition

A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol S. The subset of possible outcomes of an experiment is called an event. A sample space may contain a number of outcomes that depend on the experiment. If it contains a finite number of outcomes, then it is known as a discrete or finite sample space.

Probability of an Event

An event in probability can be defined as a set of outcomes of an experiment.
