The largest percentage of the costs incurred over the life cycle of a system is operation and support (O&S) costs. The prediction of total costs to support the life of a system or equipment plays an important role in the acquisition process during design.

There are certain key inputs in a life cycle cost (LCC) analysis, such as reliability and maintainability in determining system maintenance and support costs. Obsolences and training are just a few key elements that should be included as part of the LCC modeling.

CHAND analyzes vendor data to develop information regarding LCC, reliability, maintainability, and availability (RM&A), maintenance, provisioning, technical manuals, and training. This analysis determines the system and equipment maintenance requirements, logistic support resources required to perform maintenance tasks, tools and test equipment, repair parts, and consumables.

Additional information includes overhaul schedule and estimated cost, fuel consumption, repairability, spare parts availability, supportability, and required training.


No job is too big or too small for CHAND to entertain. In addition, we have a team of experts that can assist with identifying those hard-to-find spare items needed to support your system or equipment. Simply send CHAND your list of requirements (be it a single item or hundreds of items) and our staff will utilize their years of sourcing expertise to satisfy your needs.

Our internal database of proven suppliers consists of more than 55,000 vendors supporting over 99,000 unique parts and leased external databases containing additional sourcing information. We maintain all of this information to provide you with the right parts, when you need them, and at the right price.
