This document discusses two models for evaluating and allocating employment in metropolitan areas: 1. The Melbourne Employment Allocation Model (MEAM) allocates population-driven and strategic jobs to local government areas and activity centers based on factors like existing employment, infrastructure, and transport capacity. It provides outputs like projected job numbers and land needs for individual centers. 2. The Integrated Destination Economic Activity Model (IDEAM) evaluates the sustainability of individual centers based on metrics in areas like intensity, diversity, employment, and accessibility. It scores and compares centers to targets defined by their place in the activity center hierarchy. The goal is to identify improvement needs to move centers up the hierarchy.
