Definitions

  • This invention relates generally to a nondestructive training and analytical process, and more particularly, to one in which an elongated object dividing process is simulated so an operator can make decisions and compare his result with a predetermined result.
  • an elongaged object such as a tree-length log
  • logs are divided into segments of appropriate lengths and allocated to certain disposals depending upon the product to be generated.
  • Log merchandising systems are well known and many are in use.
  • One of the important considerations in merchandising long logs is the decision regarding segment lengths and disposals.
  • a merchandiser operator must have the decision-making ability to select the appropriately sized segments and allocate the segments to be disposed. Depending upon the array of product to be generated from the short segments, the operator must be trained and informed so he can make his decisions quickly and with a high degree of accurateness based upon preselected criteria.
  • one disposal option is to "sawlog.”
  • the appropriate length and other physical characteristics will be determined based on the requirements for cutting a log into lumber, either for maximum yield or value.
  • Another option is to "plywood.”
  • the appropriate length and other physical characteristics will be determined based on the requirements for peeling a log into veneer and manufacturing plywood.
  • Another option is to "fiber.”
  • the appropriate length and other physical characteristics will be determined based on the requirements for converting the segments into chips for pulping.
  • one object of the present invention is the provision of a nondestructive training process for teaching users skills in dividing elongated objects and allocating segments.
  • Still another object is the provision in the interactive system for the comparison display of cumulative results for a series of elongated objects.
  • the present invention is practiced in one form by providing to a user a visual display and input unit that is coupled to a programmed data processing system having a memory whereby the user can interactively simulate on the display unit an eionged object dividing and allocating process.
  • a user will first call up from memory a visual representation of an eionged object and will then decide how best to divide and allocate the object.
  • the user's decision is input to the data processor which is programmed to calculate a result for the user's decision. This result is then displayed along with a predetermined optimum result stored in memory.
  • the user thereby gains an understanding of his decision- making ability against a predetermined optimum result based on a preselected set of standards.
  • Fig. 1 is a representation of what the user may see on a screen when an eionged object is first displayed.
  • Fig. 2 is a representation of what the user sees after his first decision has been made and input to the system.
  • Fig. 3 is a representation of what the user sees after his complete decision has been made and the values calculated and displayed.
  • Fig. 4 is a representation of what the user may see on a screen after four objects have been processed and he desires to learn the cumulative results.
  • Fig. 5 is a logic flow chart outlining the steps within the process carried out on a stand-alone interactive programmed computer and visual display system.
  • a Tektronix computer and display system designated as product 4052 having 56K of memory to be suitable.
  • This particular system includes a general purpose digital computer, programmable to carry out predetermined data processing and display functions.
  • the associated video display device is capable of drawing vectors.
  • Providing the interactive means between the user and the computer system is a typical set of alpha numeric and programmable function keys arranged conveniently in a keyboard. Each key represents a separate programmable function switch that serves to control the data processing on an interruptable basis. The user controls the flow of the interactive process and provides inputs to the data processing hardware as required to carry out and complete the process.
  • the data items will be stored in the computer using convenient known storage media, although a system using magnetic tape with an associated drive means is preferred.
  • One data item is a parameter table containing information which defines the allowable assignments or allocations of segments and allowable segment lengths for each allocation. At least one allocation must be available, which will be the default decision when the user fails to specify another allocation. These allocations and lengths correspond to function switches on the display hardware. As an example , when the simulated elongated object is a long log, an appropriate potential allocation for a segment will be as a plyblock, suitable for peeling into veneer and manufacturing plywood, and having a predetermined length of approximately eight feet. Other suitable allocations and lengths will be defined based on the particular user's circumstances, including converting facilities and market conditions.
  • Another item of data will be a series of elongated objects, such as representations of long logs, containing the two dimensional outline of each object in X-Y coordinate pairs and optionally other intrisinc properties of each object.
  • the representation may include taper, curvature or sweep, and numbers and locations of knots, as well as overall length and diameter.
  • the visual representation of the stored data will be perceived by the user as, for example, a simulated long log.
  • information can be displayed to indicate the object's length and diameters.
  • each elongated object in the data file there is a predetermined preferred segmentation and allocation pattern.
  • Each pattern is specified by segment lengths and allocations.
  • Another data item is a utility table specifying the utility value of a segment of an elongated object by parameters based on the geometry and other intrinsic properties of the segment. For example, in the simulation process for long log merchandising, a plyblock having the given dimensions and characteristics will have a certain predetermined assigned dollar value stored in the utility or value table.
  • the utility table in a preferred embodiment has dollar values, but other units representing other forms of utilities for the segments may be used.
  • An additional necessary data item is an evaluation algorithm which computes in the data processor the necessary parameters for the utility table of a segment based on the position of the segment in the elongated object, the geometry of the object, and other intrinsic characteristics of the elongated object. Such an algorithm is well within the skill level of one having ordinary skill in the art to write and program into the computer.
  • Fig. 1 is an example of a visual representation of an elongated object (in the embodiment depicted a long log), and includes a title and object number block and a scale allowing the user to judge accurately the dimensions of the simulated long log.
  • the log is segmented into four foot increments again to allow the user to make more accurate estimates and decisions.
  • the log is displayed including taper with the large end on the left tapering to the small end on the right, again simulating an actual long log.
  • numbers are displayed in the object and represent the numbers and locations of knots along the simulated long log.
  • the title block and scale are omitted since they are not needed for the particular steps.
  • the user may select either a length (by activating the appropriate function key corresponding to a length) or may allocate the remainder of the object to the default allocation specified in the parameter table (also by activating the appropriate function key). If the latter is done, go to Step 9.
  • Steps 7-9 Execute the evauation algorithm using the segment of the object specified by Steps 7-9. Look up the utility value for the segment in the utility table and store the utility value along with the parameters computed for the utility table by the evaluation algorithm. Sum the utility value of the segments and store in memory.
  • Step 6 If there is more of the object for the user to divide into segments and allocate, go to Step 6; otherwise, continue to Step 12.
  • Step 14 Permit user to display (by activating the appropriate function key) information for each segment; this information consists of the parameters computed by the evaluation algorithm in Steps 10 and 13. 15. Accumulate the number of objects processed, the user utility values, and the stored preferred pattern utility values; permit user to display totals and/or to clear totals by activating appropriate function keys; go to Step 2 for additional use of interactive simulation process.
  • an exemplary display is depicted for Step 15 and includes the number of objects processed by the user, the value of optimum segmentation and allocation pattern and the value of the user-determined segmentation and allocation pattern.
  • the user may select the "stop” function switch, causing the process to stop and to display the totals as specified in Step 15. Once the process has been stopped in this manner, it may be restarted by activating the "restart" function switch.

Abstract

Un système d'entraînement visuel relativement bon marché, portatif et indépendant affiche de manière interactive des représentations bidimensionnelles d'objets allongés sur un écran de visualisation (Fig. 1). Un opérateur observe l'objet allongé et par l'intermédiaire d'un organe d'introduction de données, tel qu'un clavier alphanumérique, divise l'objet en segments et affecte les segments selon des critères présélectionnés. Les résultats de la décision de l'opérateur sont ensuite calculés dans un processeur de données programmé et sont comparés visuellement avec un résultat prédéterminé qui est stocké en mémoire pour l'objet particulier (Fig. 3).
