To help integrateactivitiesin the environmentalrestoration and waste managementmission of the Hanford Site, the Hanford IntegratedPlanning Project (HIPP) was establishedand funded by the U.S. Departmentof Energy. The project is divided into three key program elements,the first focusingon an explicit,defensibleand comprehensivemethod for evaluatingtechnical options. Based on the premise that computer technologycan be used to support the decision-makingprocess and facilitateintegrationamong programsand activities,the Decision Support Tools Task was charged with assessingthe status of computer technologyfor those purposesat the Site. The task addressed two types of tools' tools need to provide technical informationand managementsupport tools. Technical tools include performanceand risk asses'sment models, informationmanagementsystems, data and the computer infrastructureto supportsmodels, data, and informationmanagementsystems.Managementdecision support tools are used to synthesize informationat a high level to assist with making decisions.The major conclusionsresulting from the assessmentare that there is . much technical informationavailable, but it is not reaching the decisionmakers in a forr_to be used. Many existing tobls provide componentsthat are needed to integratesite activities; however, some components are missing and, more importantly,the "glue" or connectionsto tie the componentstogether to answer decision-makersquestions is largely absent. Examples that show that informationexists, but is not integratedare that I) costs of remediation options cannot be easily coupled to measures of performanceor to schedule and 2) historicaldata are recognizedas important,but no plan for their role in site remediation exists. Top priority should be given to decision support tools that support activitiesgiven in the TPA. Other decision tools are needed to facilitateand support the environmentalrestoration and waste managementmission. The prioritizationprocess for their developmentinclude addressingthe followingitems" tools that are needed regardlessof remedia_ tion options chosen; tools that have a bias for action and can be used immediatelyto help make decisions;tools that apply across multiple program areas; and tools that help implement the observationalapproach to environmentalremediation.iii EXECUTIVE SUMMARYThe primary mission at the Hanford Site has changed from producing plutonium for weapons to environmentalrestorationand waste management. J Since the late 1950s, the Site has been managed for multiple programs with separate and unrelated objectives,resulting in limited interactionsamong the programs. However, with a shift to the mission of environmentalrestoration and waste management,many programs at the Site are focused on cleanup, and the coordinationamong programs have become critical to satisfyingthe Site mission. To help integrate activitiesin environmentalrestorationand waste management,the Hanford IntegratedPlanning Project was establishedand funded by the U.S. Departmentof Energy (DOE). The Hanford Int...
