Weir S&H Consultancy Operational Logistics Analysis (OLA) is a method intended to analyse logistic systems and sub-system designs at any life-cycle stage from initial concept through detail design to in-service support and disposal

Flexible models are created that empower clients to, evaluate options; optimise performance and manpower needs, support trade-off analysis and consider "what-if" scenarios.

OLA involves the use of 3-D models underpinned by detailed mathematical logic to support discrete event simulation of representative scenarios and environments.

All variables can be analysed provided they can be allocated to discrete events / tasks performed. Typically these include performance, cost and time but can also cover availability and operator load.

Models can address the movement of both solid and fluid materiel in both internal and external flows, i.e. Nuclear Fuel Routes, Munitions (including weapon handling), Nuclear Waste Stowage, Solid stores (dry goods, solid waste) and Fluids (fuel, oil, water, liquid waste).Model outputs help justify parameters used in specifications and aid "requirements validation" - i.e. showing that the system specified, if it is verified as meeting the requirements, will perform as desired. Weir S&H can create validated videos of the system performance and output as required by the customer.
