The scheme of the embodiment can be mainly applied to a scene based on matching of personnel and tasks in a discrete manufacturing workshop, and has the main design purposes that: compared with the man-machine task scheduling mode of the existing manufacturing system, the method can objectively describe the skill level of the personnel, reflect the skill bias of different personnel, and simultaneously carry out matching calculation according to the skill of the personnel and the task content to obtain the task matching degree of objective evaluation, so that more appropriate personnel can be selected to execute the task according to the task matching degree.
An embodiment of the present invention provides a task matching method for a manufacturing shop, as shown in fig. 4, including:
and S1, extracting the personnel ID related to the workshop ID from the personnel information database according to the workshop ID, and extracting the skill information corresponding to the personnel ID.
Wherein the skill information comprises skill type information and skill weight information.
And S2, inquiring the task requirement template according to the task information, and determining the skill type and the skill weight information required by the task.
And S3, determining the personnel information of which the matching degree meets the task requirement template according to the results obtained by executing S1 and S2, and determining the personnel participating in the task.
And S4, after the task is executed, scoring the task result according to the historical task data to obtain the integral value of the personnel participating in the task.
For example: according to parameters such as error rate and success rate when personnel perform tasks, completion time of personnel and the like, corresponding functions can be set to calculate the integral value, such as: the integral value score is success rate a + (completion time/historical average completion time) b + (1-error rate) c, where a is 20, b is 60, and c is 20.
And S5, updating the skill weight information of the personnel participating in the task according to the integral value obtained by executing the S4.
In this embodiment, the skill information is recorded as a skill level tree of the person. The personnel skill level tree comprises at least one layer of skill information established on a root node, and the skill information on each layer consists of the skill type information of the layer and the skill weight information of the layer.
The personnel skill level tree is mainly used for representing skill deviation of personnel, and the visualization degree of the personnel skill level tree is high, so that the display is facilitated. And the personnel skill level tree is also convenient for database storage, and the relation among all layers in the personnel skill level tree, the skill type information and the skill weight information in all layers are only required to be stored through a database table.
And the weight value of the personnel skill level tree is recorded in the root node. Each layer established on the root node comprises at least one node, one type of skill is recorded in one node, and the weight value of the one skill is also recorded. And the weight value recorded in one father node is the sum of the weight values of all the child nodes of the father node. If one node in the first layer corresponds to at least one node in the second layer, the at least one node corresponding to the second layer is used as a child node of one node in the first layer. For example: as shown in FIG. 1, each node of the staff skill level tree is composed of skills and weights, representing the proficiency level of the corresponding skill. The node weight value of the personnel skill level tree is the sum of all child node weight values of the node, and the time complexity of inquiring the skill weight is effectively reduced. The root node in the skill level tree of the person does not represent any skill, and the weight value of the root node represents the overall skill level situation of the person.
Specifically, in the task requirement template, a task ID, and skill type information and skill weight information corresponding to the task ID are recorded. The skill type information and the skill weight information corresponding to the task ID are divided into at least two groups, each group corresponding to an execution level of a task.
Wherein the execution level of the task at least comprises: good and excellent. Or the execution level of the task is positively correlated with the processing index, and the processing index comprises the magnitude of product precision and/or the yield of the product.
Specifically, the task requirement template records the skill type and the skill mastering level required for executing the task. For different execution levels of tasks, there may be some differences between the setting of the skill type and the skill mastering level, for example, if the execution level of the task is required to be passed, the requirement for the skill mastering level may be reduced (the weight value requirement is lower than the weight average value), or for a product requiring high processing precision or a product requiring high processing yield, the requirement for the skill mastering level may be increased (the weight value requirement is higher than the weight average value), and the weight average value may be calculated by a statistical means. For example: as shown in fig. 1, each node may include a plurality of child nodes, the skills of the child nodes are categorized into parent node skill categories, and if the parent node skills are machine maintenance skills, the child nodes may be machine maintenance, milling machine maintenance, and the like, and the personnel skill level tree model may be designed according to actual needs of the workshop.
In this embodiment, step S3 includes:
and screening the personnel according to the skill weight information corresponding to the task ID. Wherein, people with irrelevant skills can be screened in advance according to the skill requirement of the task and the skill level of the people. And determining task requirement skills according to the skill type information corresponding to the task ID, and determining the requirement proportion of each kind of skill corresponding to the task ID after normalization processing. Multiplying the demand proportion of each type of skill corresponding to the task ID by the weight value of each type of skill corresponding to the task ID, and then summing all multiplication results to obtain a first matching degree. For example: as shown in fig. 2, each person task includes task details and skill requirements, the person is screened according to the weight of the skill requirements, the skill requirements are normalized, the requirement proportion of each skill is calculated, the screened person calculates the matching degree according to the two parts of the task requirement skills and the non-task requirement skills, and the total matching degree is the sum of the two parts. And multiplying the task requirement skill part by the skill ratio and the corresponding skill weight and summing the result to obtain the matching degree of the task requirement skill part. For example: in this embodiment, a quality matching formula may be adopted, and the following formula is given mainly by referring to the person level skill tree model:
m(wi,tj)=δ1(wi,tj)+δ2(wi,tj) Wherein, delta1(wi,tj) Represents a person wiFor task tjThe value of the influence of the degree of skill in the requirement on the task match, δ2(wi,tj) Represents a person wiFor non-task tjThe influence value of the skill mastery degree in the requirement on the task matching, wherein sigma (0)<σ<1) Is a reduction factor which indicates that the further the distance between two skills is, the weaker the degree of association between them, for the interpretation of some other of them: s ═ S, [ S [1 ]],s[2],…,s[k]]Where S is the root node, S1],s[2],…,s[k]Is a subtree under the root node. Each node S belongs to S and corresponds to a key value pair<k(s),d(s)>Where k(s) represents a skill and d(s) represents a weight of the skill. For each node S ∈ S, we denote its depth in S, fast, (S)(n)(s) (0. ltoreq. n.ltoreq. depth (s)) represents a parent node n levels higher than s, child(s) represents a set of child nodes of s. For a certain skill s of a worker wi in HST, his weight is the sum of his sub-skill weights, i.e.:
in the formula
Representing the weight of the person wi with respect to the skill s,
representing the sub-skill weights of the person wi with respect to the skill s.
For each task t
jE.g. T, we define a set of task requirements
Wherein s is
iRepresenting the skills of the non-root nodes. All task requirements are defined by the task publisher in advanceTo make the description of the task clearer, we require that stricter constraints be added to the skill set of the task requirements. In task demand collection
In (3), there is no parent-child or ancestor relationship between elements, i.e.:
representing a task t
jMiddle skill s
iThe percentage of (b) is as follows:
m(wi,tj) To describe a person wiAnd task tjThe degree of match between them is called the match quality.
Theoretically, each node in the HST has a path to any skill, but most of the skills are far away, and the influence of the skills is reduced to be extremely small or even negligible. So in practice it can be simply assumed that all effects originate from a common ancestor node.
Further, the method also comprises the following steps: and determining the skill required by the non-task according to the skill information corresponding to the personnel ID of the screened personnel and the determined task required skill. And calculating the attenuation coefficient according to the distance relation of skills in the staff skill level tree model. And acquiring a second matching degree by using the attenuation coefficient, the demand ratio of each type of technology corresponding to the task ID and the weight value of each type of technology corresponding to the task ID. And taking the sum of the first matching degree and the second matching degree as the matching degree of the personnel relative to the task.
For the non-task requirement skill part, calculating an attenuation coefficient according to the distance relation of skills in the personnel skill level tree model, and performing task matching on the non-task requirement skill part by using the attenuation coefficient, the skill proportion and the skill weight. For example:
as shown in fig. 2, each person task includes task details and skill requirements, the person is screened according to the weight of the skill requirements, the skill requirements are normalized, the requirement proportion of each skill is calculated, the screened person calculates the matching degree according to the two parts of the task requirement skills and the non-task requirement skills, and the total matching degree is the sum of the two parts. And multiplying the task requirement skill part by the skill ratio and the corresponding skill weight and summing the result to obtain the matching degree of the task requirement skill part. And for the non-task requirement skill part, calculating attenuation coefficients according to the distance relation of skills in the personnel skill level tree model, and performing task matching on the non-task requirement skill part by using the attenuation coefficients, the skill proportion and the skill weight.
As shown in fig. 3, the personnel executes the completed task according to the requirement, and the result of the task is evaluated according to the historical completion condition of the personnel in the task workshop. And returning a point value to the personnel according to the quality of the result, wherein the point value can be positive or negative, a positive value represents the skill reward of the personnel, and a negative value represents the skill punishment of the personnel. And distributing the integral value according to the proportion condition of each skill in the task requirement skills, and directly updating the integral value into the weight value of the corresponding skill node. For each updated skill node, since its weight value is the sum of all child node weight values, the weight needs to be updated recursively for the child nodes, and all child nodes are equally assigned the integral value of the parent node.
The scheme in the prior art which does not fully consider the matching degree of the personnel and the current task is adopted. In the embodiment, a scheme capable of describing matching calculation of the personnel capacity system and the tasks is designed, so that the tasks are reasonably distributed according to the personnel capacity, and the efficiency of executing the tasks by the personnel is improved.

And the task matching degree analysis module is used for determining the personnel information of the template with matching degree meeting the task requirement and determining the personnel participating in the task.
The task matching degree analysis module is used for calculating the matching degree between the workshop staff and the task and calculating the matching degree of related skills of the staff according to the skill requirement proportion of the task content. Meanwhile, the relevance of skills is considered, and the skills required by non-tasks are also added into the matching degree calculation, so that the influence caused by the skill level of the personnel can be more objectively described.
