63 Cards in this Set

  • Front
  • Back
identify a relationship between two factors, one that precedes and causes changes in the second or effect factors
Causal relationships
measures the amount of variation in the dependent variable that the regression line explains
coefficient of determination, r2
a group of business processes supported by information technology where supply chain members agree to shared business objectives and measures, develop joint sales and operational plans, and collaborate electronically to generate and revise forecasts and production plans
Collaborative planning, forecasting and replenishment (CPFR)
r, measures the strength and direction of the relationship between the independent variable X and the dependent variable Y
correlation coefficient
measures total forecast error
cumulative sum of forecast errors (CFE)
uses a team of experts to develop a consensus forecast
Delphi method
calculates forecasts by giving more weight to recent demands than to earlier demands
Exponential smoothing
the difference between the forecast and the actual demand for a given period
Forecast error
statistical technique that expresses the forecast variable as a linear function of one or more independent variables
Linear regression
a systematic approach to measure customer interest in a service or product through data-gathering surveys
Market research
a measure that reports error in proportion to the demand
a measure that reports error in proportion to the demand
measure that reports error in proportion to the demand
Mean absolute percentage error
all measure the dispersion of forecast errors
Mean square error (MSE), standard deviation (Ã), and mean absolute deviation (MAD)
a technique for estimating the average of a demand series and filtering out the effects of random variation
Moving average
a method that calculates seasonal factors that are multiplied by an estimate of the average demand to develop a seasonal forecast
multiplicative seasonal method
uses the demand for the current period as the forecast for the next period.
naïve forecast
based on subjective factors, estimates, and opinions
Qualitative forecasting
utilizes an integrated circuit and a tag antenna printed on a tag to transmit and record information on a product
Radio Frequency Identification (RFID)
involves gathering the opinions of sales people and managers for a particular product or family of products
Salesforce planning
percentage of the average demand
seasonal index
measures the distance between dependent variable and the regression line
standard error of the estimate, syx
utilizes past demand data to predict future demand by examining cyclical, trend, and seasonal influences
Time series analysis
a technique that allows periods to have different weights with the total weight equaling 1.0 (one)
Weighted moving average
identify a relationship between two factors, one that precedes and causes changes in the second or effect factors
Causal relationships
measures the amount of variation in the dependent variable that the regression line explains
coefficient of determination, r2
the technique of assigning work to individual stations so that the variability across all stations in an assembly line is minimized.
Assembly line balancing
a higher volume job shop, in which the same or similar products are produced repetitively
Batch process
the step with the slowest cycle time in a given process. This is the limiting step that limits productivity for the process
bottleneck
a basic mathematical technique that allows a comparison of total costs for different processes .
Break-even Analysis
high volume, low flexibility and work with non-discrete items that are not divided into their final packages until the very end of production
Continuous processes
the degree to which customers are involved in shaping the end service/product that the customer receives
Customer involvement
the time it takes to complete that step/action one time
cycle time
requires the product (due to its extreme weight or size) to remain at its location
fixed-position layout
involves graphically portraying the key elements, steps, participants, and materials of a process
Flowcharting
shows the number of trips or the amount of materials flowing between different departments or workcenters
From-to Charts
provides a visual representation of schedules for the resources used in a particular process
Gantt chart
an approach in which the product parts having similarities (shape, usage and/or manufacturing process) are grouped together to achieve higher level of integration between the product design and manufacturing
Group technology
attempt to combine the advantages of process and product layouts by grouping disparate machines into work centers or cells to work on products that have similar shapes and processing requirements.
Hybrid layouts
a process that provides high flexibility to produce a variety of products in limited
Job Shop
the amount of labor needed to provide a service relative to the total amount of physical resources.
Labor intensity
the point at which customers lose physical sight of the steps in a particular process. Separates front-office operations that directly interact with customers from back-office operations that are more independent.
line of visibility
have high volumes, standardized products, and dedicated resources
Line processes
a weighted calculation of the load times the distance covered
Load * Distance Score
have low customer contact/customization in combination with high labor intensity
Mass Services
the number of units that can be produced per unit of time
output
nvolves selecting suppliers with an expertise in a particular area of business to produce and deliver a component part or service to another company
Outsourcing
involves numerous decisions regarding relationships between workers, technology, raw materials and job assignments
Process choice
group machines, equipment, or people with similar functions or goals together
Process layouts
employs computer software to develop a visual model of a process that incorporates multiple workcenters, inputs and processing techniques as variables
Process Simulation
dedicates equipment and workers to specific products on a linear route
Product layout
matches the product life-cycle stage (ranging from low volume-low standardization products to high volume-high standardization commodity products) with the appropriate choice of production process
Product-Process Matrix
have both high customer contact/customization and a high degree of labor intensity
Professional services
possesses a high degree of customization, large project scope, high degree of customer involvement, and the use of primarily generalized tools and equipment
Project process
involves a shift from a functional perspective of the business to a process-oriented perspective
Reengineering
includes customers in the process in a way that reduces the resource demands on the organization providing the product or service while also providing the customer with improved service
Self-sourcing
includes customers in the process in a way that reduces the resource demands on the organization providing the product or service while also providing the customer with improved service
Self-sourcing
includes customers in the process in a way that reduces the resource demands on the organization providing the product or service while also providing the customer with improved service
Self-sourcing
a technique for describing and analyzing a service that incorporates both customer and server actions.
