SCperf (version 1.1.1)

SCperf-deprecated: Supply Chain Performance

Description

Computes the bullwhip effect for an stationary ARMA(p,q) demand process.

Usage

SCperf(phi, theta, L, SL)

Arguments

phi

A vector of autoregressive parameters

theta

A vector of moving-average parameters

L

A positive lead-time

SL

Service level, (default:0.95)

Value

Analytical measure for the bullwhip effect

Details

The SCperf function has been deprecated and will be made defunct; use the bullwhipgame package.
