Accounting for complexity in costing high technology manufacturing

Article Abstract:

A new type of costing unit called the Total Net Die Equivalent (TNDE), which adjusts plant output after taking into account operations complexity is proposed. With the TNDE, the longitudinal analysis of cost behavior is no longer restricted to stead-state or static manufacturing operations. The model is a flexible system that can be used for analysis and planning of high technology manufacturing operations.

Stochastic models and variable returns to scales in data envelopment analysis

Article Abstract:

Stochastic Data Envelopment Analysis (DEA) models may allow for two-sided random disturbances in input-output data. The stochastic efficiency of Decision Making Unit (DMU), on the other hand, are attributed with the chance constrained programming type formulation. Under a single random factor, parameter estimations decrease and dual form of deterministic equivalent is evident.

Chance constrained programming approaches to congestion in stochastic data environment analysis

Article Abstract:

An attempt is made for treating congestion in data envelopment analysis (DEA) using models that are extended by according them chance constrained programming formulations. Further simplifying assumptions that allow us to identify conditions under which appearances of congestion with associated probabilities can be determined in a straightforward manner are introduced.
