In terms of the second stage of model development, the implementation of an operational simulation model can be facilitated by custom-tailored or readily available "off-the-shelf" software (Robinson, 2004). Considering the level of sophistication and ease of use offered by the latter method, as well as the significant amount of resources required to obtain adequate programming language skills, it was decided that a specialist simulation software would be the more efficient software approach. Thus, the conceptual model was implemented using Simul8 (Visual8 Corporation), a commercial off-the-shelf discrete-event simulation package using the information illustrated in Table I.
