What is a WMS/CMMS?

  • There 1,440 minutes in a day. For the next 12ish years, each minute inside

the dome should be allocated for and assigned to someone, on at least a weekly basis.

  • Account for time to stage large equipment, adjust environmental

conditions for tests, order parts, etc.

  • There will inevitably be a backlog so we will never run out of tasks to

fill the schedule.

  • Coordination of schedules for Planned Maintenance (Astronomers, Operators,

Engineers, Safety, Maintenance Technicians, Contractors)

  • Interface to Issue Management System for handling Unplanned Maintenance.
  • Interface to Inventory Management system for parts and materials ordering.
  • Monitor trends, generate daily reports and ad-hoc alarms as needed.

Needs for a Work Management System

  • Commissioning and Operations work on weekly and daily timescales needs to be planned.
  • Multiple Inputs:
  • Planned Work
  • Integration
  • Verification/Commissioning
  • Engineering
  • Maintenance
  • Calibration
  • Observing
  • Unplanned Work
  • Repairs
  • Issue Resolution
  • Priorities will change sometimes from day-to-day based on real time events.
  • A common, agile tool is needed to manage all of these inputs and plan work in a coherent

and safe manner.

What is the project deliverable?

LSE-30 OS-REQ-0077 04 Maintenance Activity Support Specification: In support of all maintenance activity, both predictive and preventive, the LSST Observatory shall implement the following systems:

  • Comprehensive problem reporting, tracking, and management system
  • Work order driven preventive maintenance support system (usually known as CMMS for

Computerized Maintenance Management System).

  • Warehouse inventory and property control
  • Document control center
  • Analysis tools for supporting predictive maintenance.

One Subsystem…

LSE-61 TLS-REQ-0136 Telescope and Site Activity Support, Tracking and Reporting The Telescope and Site shall implement the following systems: Specification same as LSE-30, plus: The Telescope and Site shall maintain a permanent record of the description and time required to recover from all maintenance events. A set of automatic reports based on engineering telemetry shall be generated on a daily basis. NOTE: This requirement corresponds mostly to the OCS domain. T&S shall provide the necessary information to OCS for the maintenance management.

What is a Work Order?

Work Order = Task + Resources

  • Tasks include: replacing coolant, updating software, cleaning

glass, etc.

  • Resources include: skilled people, procedures, facilities,

consumables, parts, tools, power equipment, etc.

Varieties of CMMS Implementation

SAP-like Excel + Excellence

  • Large amount of effort and resources
  • Typically team of 30+ members for a year
  • r more
  • Large cost
  • Significant ongoing maintenance cost
  • Significant cost of implementing change
  • Large training effort involved
  • Heavily dependent on individual people,

representing a single point of failure and long ramp up for replacements or supplements.

  • Little or no integration of tools, requiring other

SMEs for different types of tools.

LSST (AURA)-Hybrid

  • Reduced initial cost due to use of existing tools

and processes.

  • Reduced ongoing maintenance costs due to use
  • f existing tools and contracts.
  • Challenges include the population of data and

integration of systems.

A Common Tool for the Life of LSST

Plan of the Day Workflow for Operations Workflow Inputs for Commissioning Daily Tasks

System Level Verification Plans Technical Optimization of System Operations Scientifically Motivated Performance Characterization Emergent Technical Issues

Scheduled Maintenance

In-situ Issue Resolution

  • LSST will develop a single tool that meets the Work Management

needs during Commissioning and Operations.

Challenges

  • Deliverable description (capability of system)
  • Development, verification and control of the BOM, as well as

the many maintenance and safety procedures.

  • Population and control of parts lists
  • Procurement pipeline and supply chain
  • Some parts and materials take longer to reach Chile
  • Some materials have restrictions

Road Map

  • Clarify project expectations.
  • What is the deliverable? Processes, Tools, Procedures, Infrastructure,

etc.

  • Specification/Requirements development and approval.
  • Tool design and review, procurement, planning, resource allocation
  • Implementation, population and verification
  • Plan for maintenance of the system (updates, process implementation an

changes in tool).

requirements (specifications & ICDs)

  • Source of all Verification Plans
  • Source of data for Verification Matrices

Verification in WMS – Syndeia Inter-Tool Element Transformations

  • Auto-generates Verification Tickets in JIRA from MagicDraw VerificationPlan elements

and attributes

  • Two-way synchronization
  • Feeds verification results to MagicDraw to generate final verification matrices (VM-F)
  • Verification is a component of Maintenance and has parallel and interlinking processes.

cases)

  • Generate Maintenance Steps (scripts) for each Task

(Plan)

  • Sequence Tasks into Maintenance Worklists
  • Execute Worklists

JIRA Workflow for Maintenance Tickets

  • System Maintenance Team (SysMT)

responsible for upfront planning

  • Generation of Maintenance Plans
  • Mapping to Acceptance and

Closeout Events (Tasks)

  • Definition of Closeout Events

CCT SysMT SysMT SysMT + Systems Scientist

  • Tickets get assigned to individuals

responsible for the work. SysMT executes the Closeout Events and Analyzes Results

  • SysMT works with the Systems Scientist

and Shift Lead to Schedule activities

  • SysMT Reviews the results and makes the

determination on the sufficiency of the results to close out the Closeout Event

  • SysMT tracks closeout progress

#lsst2018

Considerations During Implementation

  • Cross agency (observatories) cooperation. Similar activities, process, maintenance

procedures, safety, quality processes and engineering tools are currently independently developed and “uniquely” implemented.

  • Effort (and other resources) expended to develop and refine working processes and tools

may be shared.

  • Preserve this organizational (AURA-wide) legacy for ongoing and future projects
  • Mandatory Organizational Processes and Tools to be developed, purchased…or shared.
  • Management/Planning/Scheduling/Budgeting
  • Maintenance, Repairs and Issues
  • Quality, Manufacturing and Procurement Processes, Safety Policies and Implementation
  • Configuration Management (Mission critical documentation, Drawings, Software, etc.
  • Resource Coordination (specialized equipment staging, calibrations, etc.)
