AVEVA Asset Strategy Optimization setup

Introduction

AVEVA Asset Strategy Optimization (hereafter referred to as Asset Strategy Optimization) offers a powerful palette of modules that support different facets of APM (Asset Performance Management). All data is stored in a database that may be on the same PC as Asset Strategy Optimization, or on a separate server, allowing multiple users to jointly use the same data.

FMECA

The base is formed by the FMECA tree. The acronym FMECA stands for Failure Mode, Effects, and Criticality Analysis. This is an analytical model that helps you assess all failure modes of your equipment that have a high probability of happening while having serious consequences for your business objectives. Based on knowledge gained by such an assessment, if desired, mitigating measures can be taken. We speak of a FMECA tree because your systems are listed in Asset Strategy Optimization where they are broken down into a tree-structure of subsystems, parts and components. For each component it is then recorded what function it has in the context of its operating context, and how its function can fail. You then establish all causes of failure, indicating the mitigating actions in terms of repairs or maintenance actions that should be taken to prevent the failure from happening. Costs and spares can be included in the equation. The result is an accurate view of the effectivity of the existing maintenance process and a plan of how to improve the maintenance strategy.

For an introduction to FMECA and how Asset Strategy Optimization supports, read the FMECA-introduction.

Risk matrix

The results from a FMECA study are shown in the form of a risk matrix, which is constructed of two axes. One axis shows the time and on the other axis, the business goals are plotted. Both the time periods and the business goals are defined in Asset Strategy Optimization and can be different for each managed FMECA System. Company Objectives are the goals pursued by a company and on which maintenance is focused.

Examples: Environment, availability, safety, health.

FM Library

The FM Library (FM stands for FMECA) contains a set of templates that enable the user to build or extend the FMECA tree. Once created, details may be added to the various objects. Copying can be done one template at a time, or in bulk, by using the template copier. Templates can be built from scratch, by copying existing parts of the FMECA tree to the FM Library, or by applying elements of the optional industry standard libraries.

Optional Stock Management module

The optional spare parts management module adds an important aspect to the FMECA model. It offers the opportunity to incorporate the effect of stock on the maintenance strategy by influencing the total downtime. Moreover, an overview can demonstrate whether it is sensible to stock certain parts or components for economic reasons.

Simulation

The functions explained above make it possible to set out a maintenance strategy based on failure behavior and its effects on operation of your equipment. During this process, a lot of assumptions are made. To verify these assumptions the optional simulation module can be used. This module allows for comparing different scenarios, using the Monte Carlo method. Based on the results, the maintenance strategy can be further optimized. Moreover, the simulation results can be used as part of a business case to introduce a new maintenance strategy.

Other Modules

Apart from the above main components, Asset Strategy Optimization supports other powerful modules. Some come with the basic installation, others can be ordered as optional modules.

Property Grid and Property Form

The Property Grid, Scenario screen and Property Form play an important role in defining the elements in the FMECA screen and the FM Library. These are panes on the screen where the various property fields are filled and maintained. The function of both types is the same; they can be used interchangeably, and it is mostly a preference of the user which type to use.

Differences in screen lay-out

Asset Strategy Optimization, when installed, is first configured to the specific desires of the company. When optional modules are purchased and installed, this may impact the way screens look in Asset Strategy Optimization, since the influence of the new modules can be on existing screens or panels. For example, tabs can be added on property screens, or more options can be available in the options screens. As such, the screenshots the user may find in this online help may be somewhat different compared to what the user will see on the installed version of Asset Strategy Optimization.
