In the menu structure specified for SATCONl ( G \ J l m e n u ( S a t C o n L a b ) ) (see Figure 4.13), there is only a single interaction that modifies the scope attributes of a satellite construction schedule - the one in which the student generates scope and SATCONl prompts for the student to state the scope that he or she has generated. There are five interactions in this category ‘C om ponents...’, ‘Stores...’ etc., since five types of m ilitary system are involved in satellite construction - com ponents of the satellite, stores, w orkforce, vehicles (for transporting com ponents around the construction area) and construction tools. There is only a single interaction that

modifies the content attribute of the Satellite Construction Schedule - the one in which SATCONl generates content according to the student's specification. There are three satellite construction scheduling

interactions in this group ‘G enerate’, ‘Cycle by C ycle’ and ‘Ask for Info’, since SATCONl may generate a com plete schedule automatically, one cycle at a time, or until additional inform ation is required from the student. There are two groups of interactions that modify the view attributes of the satellite construction schedule: (i) those which change the 'view Type' attribute. The 'viewType' attribute of UCL's sim plified satellite construction schedules may take three values - a text list, a gantt chart, a 3-D view of the satellite (in some stage of com pletion) and resource utilisation; and (ii) those which change 'view O ptions' attributes, that is, 'view C ontentO ptions' and 'view F o rm atO p tion s'.
