About the MHE Taxonomy

 

This material handling equipment (MHE) taxonomy was created by Michael G. Kay for use in IE 453: Facilities Design and IE 753: Material Handling Systems at North Carolina State University. The taxonomy is adapted from the MHE classifications presented in Table 1 of Chu et al. [1] and Section 6.6 of Tompkins et al. [2]. Although not explicitly cited, much of the information provided for each type of equipment has been culled from the following primary sources: Tompkins et al. [2], Kulwiec [3], Konz [4], and Ward [5].

Using the Taxonomy as an Educational Tool

This taxonomy is not intended to be as comprehensive as, for example, Ward's [5] taxonomy. Instead, it is intended to provide a finite amount of information about the most common types of material handling equipment to students unfamiliar with material handling terminology. This taxonomy can be used to provide a bounded amount of material that students can be expected to memorize for a 10 to 15 question 30-minute closed-book portion of an exam.

Suggested types of exam questions include the following:

What is a principal difference between MHE x and MHE y?; e.g., describe a principal difference between a pallet jack and a pallet truck.
Describe one advantage and one disadvantage of using MHE x as opposed to MHE y; e.g., describe one advantage and one disadvantage of using a slipsheet as opposed to a pallet to support a unit load.
Determine a particular type of MHE given its characteristics; e.g., what type of industrial truck is not used to transport material?
Given the characteristics of a particular move, is MHE x or MHE y likely to be the most appropriate type of equipment? Explain your answer. For example, describe why, as compared to a pallet jack or counterbalanced lift truck, a walkie stacker is likely to be the most economical and/or technically feasible for infrequent, short-distance moves of pallets from a loading dock to pallet racks.
List n types of MHE of a particular kind; e.g., list five different types of bulk handling conveyors.
Visual identification, by name, of line drawings of MHE, where only the figures from the taxonomy are presented.
