Human Task Simulation 2 (MHT)
DELMIA Human Task Simulation is a powerful human modelling tool used to create, validate, and simulate activities for workers using the DPM planning and simulation infrastructure. Worker processes are analyzed within the context of a PPR environment to visualize how a worker , or combination of workers , will interact with both products and processes. DELMIA Human Task Simulation is deployed as an add-on product to DPM Assembly in marketing bundles or as an add-on to Human Builder.

Product Overview

DELMIA Human Task Simulation 2 (MHT) is a powerful human modelling tool used to create, validate, and simulate activities for "workers" using the DPM planning and simulation infrastructure. Workers perform these activities within the PPR environment where they may walk to a specific location (across floors, up ladders, down stairs) based on time parameters defined by the user, move from one target posture to another, as wells as pick and place parts in the work area by following the movements and paths of objects. These activities can be combined with DPM Assembly activities to analyze the relationship between workers and other entities within the simulation. They can be simulated and validated using the powerful process simulation capabilities within DPM, allowing the user to test multiple alternatives for the work humans must accomplish in a specific manufacturing, maintainability and assembly environment.

Workers can be imported as a resource or a product. It is advised, however, to import them as resources as typically they are going to be performing the process and are, therefore, acting logically as resources for this process. This is particularly important in the context of the Resource Centric Model introduced in R10, which aims to make the process of creating, storing and re-using task simulations far more intuitive. More than one worker can be imported for a process; parallel activities can be created and simulated using the Human Task Simulation 2 (MHT) workbench. A worker (manikin) must have already been created in the Human Builder 2 (MHB) product and saved as a CATProduct file. In the case of Human Task Simulation 2 (MHT), the target is to create a process that will apply to worker activities. In a walking activity, the worker must walk on a surface to support its steps as it walks to a target. Such surfaces need to be imported as resources in the PPR tree. Other resources could be tables or fixtures on which the user will position parts and tools, and the tools the worker needs to use to perform the task. It is possible to save manikin attributes and activities inside Catalogs .

Human Task Simulation 2 (MHT) was introduced as a new General Availability (GA) product in V5R9 and has been incrementally advanced over all subsequent releases. It represents an important component in the Resource Modeling and Simulation paradigm within the DELMIA V5 suite of solutions.

Human Task Simulation 2 (MHT) addresses the needs of manufacturing engineers, process planners, maintainability engineers and concept designers from the aerospace, automotive, plant design, heavy engineering, ship building and electrical goods industries.

Human Task Simulation 2 (MHT) requires that Human Builder 2 (MHB) is installed and licensed. In addition, MHT is also effectively used in conjunction with Human Measurements Editor 2 (MHM), Human Posture Analysis 2 (MHP) and Human Activity Analysis 2 (MHA) for advanced detailed digital human creation and analysis, improved human comfort, performance, and safety. These products are combined with DPM assembly (AP2) to create a fully integrated manufacturing and assembly solution. In addition, MHT is available an an integral part of the Human Modeling Complete and Human Basic Activities Marketing Bundles.

This BFS is to be read in conjunction with the following DELMIA BFS documents that describe the standard procedures for creating, manipulating and analyzing worker manikins and assumes the user is familiar with the DELMIA suite of V5 DPM solutions.

Product Highlights

Ladder Climbing
This feature provides the ability to generate postures to make the Worker perform ladder climbing with uniform rung spacing. The simulation requires that the worker is positioned near the first rung-edge of the ladder. The user then specifies the edges of the first and second rungs on the ladder and then specifies the number of rungs to be climbed. Ladder climbing parameters can be edited after creation. A sequenced set of MoveToPosture activities are automatically generated.

Stair Climbing
This feature provides the ability to generate postures to make the Worker perform stair climbing with uniform rung spacing. The simulation requires that the worker is positioned near the first step-edge of the stairs. The user then specifies the edges of the first and second steps on the stairs and then specifies the number of stairs to be climbed. Stair climbing parameters can be edited after creation, including the type of arm movement (swing) that is required. A sequenced set of MoveToPosture activities are automatically generated.

Line Tracking
This feature provides the ability to simulate workers who are working alongside a moving element (for example, an automotive assembly line). To utilize the line tracking feature, the user needs only to create a simulation against the static (not moving) object on the line. By assigning system speed and direction of object motion the system automatically considers the object movement in the human simulation and adjusts the human motion so that the manikin can work at the same position as created for the initial static object. A Fetch activity during line tracking will be supported using the Autowalk command with user-imposed walk time which will estimate the right walking path to and from the moving object in the event that the worker is required to temporarily leave the line (for example, to retrieve an item from a Parts Bin).

Energy Expenditure
This feature provides the ability to estimate the energy consumption in kilocalories (kcal) for high-exertion tasks based on the published experimental data of Dr. Arun Garg. This command is currently applicable to one single task at a time and requires the specification of certain task parameters by the user. The Energy Expenditure function permits the user to specify the actions (sequence of operations or MoveToPostures) and its associated parameters (Body Posture, Body Action, Left Arm Action, Right Arm Action). Once these input variables have been specified, the system begins computing the energy prediction data and displays out a report in a separate window. NOTE: This command requires that the User has the appropriate MHA license.

Cut/Copy/Paste of Task Enhancements
This feature provides the ability to cut/copy/paste human simulation tasks and activities. Includes the capability to re-establish items (picked part, walk plane) and attributes (walk curve points) at the time of copy/paste. In addition, it is possible to copy/paste tasks and activities across documents and ensure the same behavior for re-use of tasks from catalog and copy/paste functions.

Enhanced Integration of Commands
This feature provides the appropriate tools from Human Builder available inside Human Task Simulation Workbench, thereby reducing the time necessary to complete a human simulation as well as greatly enhancing the intuitiveness of task creation. Commands available directly within the MHT Workbench itself: Calculate Reach Envelope and Collision Detection while moving Manikin Segments in IK, FK and Reach mode. Commands available during MoveToPosture activity creation or modification: Save posture in .swl library, Save posture in Posture Catalog, Collision Detection while moving Manikin Segments in IK, FK and Reach mode, Place Mode, Ability to Move Human and Parts in the environment, Open Vision window, Access to manikin properties, Body Posture Reset/Swap, Local Posture Reset/Mirror/Copy/Swap, Global and Local Posture Copy/Paste, Manikin Copy/Paste (ability to copy Postures from one manikin to another) and Redefine Offset on Segment.
