Analysis and evaluation of computer support for afloat submarine IMA maintenance planning

Abstract

Late identification of work and inadequate administrative controls are principle causes of untimely preparation of Controlled Work Procedures (CWPs) at one heavily loaded, afloat, submarine Intermediate Maintenance Activity (IMA). Untimely CWP preparation, however, is symptomatic of a more widespread problem of inadequate communications and decision support in the IMA maintenance planning process. The Maintenance Resource Management System's (MRMS) Engineered Time Value standards provide significant improvement in resource estimation accuracy over the Maintenance and Material Management (3-M) Intermediate Maintenance Management System (IMMS). However, both IMMS and MRMS (version 0) emphasize transaction processing and structured, upline reporting. Neither system provides tools necessary for optimal decision making to IMA maintenance supervisors.
