Description

[0001] APPARATUS AND METHOD FOR DESIGNING PRODUCT SERVICE SYSTEM [0002]

The present invention relates to a PSS design apparatus and method.

Recently, there has been a growing interest in enhancing corporate competitiveness by coping with the paradigm shift of services and creating new business models. To this end, companies are looking for a holistic solution to find consumer needs and actively meet them. Also, the center of corporate competitiveness is shifting from products, which are physical things, to services related to human values.

To cope with these changes, research is being conducted on the design of a Product Service System (PSS) that integrates product elements and service elements organically to deliver higher value to a variety of stakeholders.

PSS design is a fusion design process that includes new PSS planning, concept design, and implementation design. In other words, PSS design is a process that includes planning, design, and design. It reaffirms the competitiveness of products and technologies of manufacturing companies and identifies the value of future-oriented consumer perspectives. In addition, the lack of competitiveness of manufacturing companies can be complemented by outsourcing from the outside, so that a business model based on PSS in which product elements and service elements are systematically mapped can be created.

The above-mentioned method of combining the product element and the service element includes a method of 'productization of the product' in which a service element is added to the existing product and a method of 'productization of the service' in which a physical product element such as automation is added to the existing service have. For example, there are bicycle lending systems as products for services, and automatic cash dispensers for automating banking services as commercialization examples of services.

As such, the PSS may refer to a service that provides after-sale management of a product or consulting on a product after allowing the product to be rented to a consumer free of charge, for example, simply from the method of selling the product, and purchasing the right to use the product. In addition, PSS integrates products and services to maintain a positive attitude toward the consumers of the enterprise and to maintain the company's competitiveness.

However, since the conventional PSS design often relies on the developer's sense or intuition, there is a limitation in applying the service to the product, and the product element and the service element are organically fused so that the design and development The computer-based PSS design process is not supported.

Korean Patent Laid-Open Publication No. 2006-0068162 (entitled "Product series based software development method") discloses various types of core assets (architectures, design models, components, etc.) So as to be reusable.

An embodiment of the present invention is a PSS design device for efficiently developing a PSS by efficiently performing a PSS design process developed based on a mutual relation between an actor, a function, a related person information, a product element, and a service element And methods.

According to an aspect of the present invention, there is provided a method of designing a PSS, the method comprising the steps of: (a) determining a target value mapped to requirements and requirements of a plurality of parties related to a product-service system (PSS) (B) performing behavioral modeling that defines associations between the actors of the parties based on the interactions between the actors of the parties involved; (c) the high-level functions of the PSS implementing the requirements and the goal value; and Performing PSS function modeling to define a higher related party mapped to the function and to divide the higher function and the higher related party into one or more sub-functions and sub-associates mapped to the lower function; and (d) (c) mapping the at least one of the product element and the service element to the behavior, function, and related information of the related person defined in step (c) according to the correlation, thereby creating a PSS concept It should.

In addition, the PSS design apparatus according to an embodiment of the present invention includes a requirement definition unit that defines a target value mapped to requirements and requirements of a plurality of related parties related to a PSS (Product-Service System) A behavior modeling unit that performs behavior modeling that defines the association between the actors of the related parties based on the relevance, a parent function mapped to the parent function and the parent function of the PSS that implements the requirements and the target value, A PSS function modeling unit that defines subordinate associates that are mapped to subordinate functions and subordinate functions by dividing the related persons into one or more, and a product element and a service element in the behavior, function, and related information of a related person defined through the behavior modeling unit and the PSS function modeling unit To generate a PSS concept image by mapping the PSS concept image according to the correlation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

FIG. 1 illustrates a scenario illustrating an experience of donating a used second-hand garment in a specific situation illustrated by way of example to explain a PSS design process according to an embodiment of the present invention.

For example, suppose that a used garment collection box (12) (product) is installed in a shabby corner of an alley street, and a service for recycling used garments is performed using the garment collection box. And on a rainy day, there is a garment provider 10 to donate garments to a used garbage can 12 located at the shabby corner of a back street, and sometimes a cat roaming around the garbage collector 12.

In the above situation, the negative emotional experience value can be obtained from the current shabby used garment collector 12. And a poor physical situation will reduce the positive emotional experience value of voluntary apparel donation. The garments collected from the above-described garment collecting box 12 have been treated as garbage, and some usable garments can be sorted by the hard work of the workers 14. [ After identifying the negative value obtained by contacting such a shabby used garment collector 12, the design of a product-service integration system (hereinafter referred to as "PSS") begins to translate negative experience values into positive experience values .

In addition, a new PSS concept proposal that enhances the experience value of the apparel provider 10 and the beneficiary 20 based on the above-described situation is created by designing the behavior. For example, considering the garment collection PSS installed at a local residence hall or a convenience store, the concept can lead to a variety of new behaviors of the apparel provider 10. That is, if a physical situation is changed, a new service action that promotes a certain target value can be effectively generated.

For example, similar behaviors and attributes associated with giving his niece a gift of his / her son's gift can be created in a new concept. In addition, the apparel packaging behavior may be added to the behavior of the apparel provider 10. Then, the behavior of the apparel provider 10 that cleanes and repairs used clothes can be added to the new concept.

Figure 2 shows a scenario illustrating a new garbage collection PSS.

Subsequently, the actions added to the new concept are mapped (or linked) to the sub-functions (sub-functions) from the overall function (upper function) of "garment collection and supply". The relevance of these behaviors and functions is indicated in the function-related service blueprint described below. And functional requirements to accommodate specific behaviors can be perceived as a feature of prototypes. At the garment collection PSS station 30, the act of inputting information to donate the garment is performed on a small screen located at the upper left of the station 30. Then, after the clothing photograph is taken by the camera located at the upper part of the large screen, a guide for clothing packaging is provided on the large screen.

Here, when packaging the garment, the apparel provider 10 uses the appropriate packaging box provided by the box providing module of the station 30. Then, the apparel provider 10 prints a bar code sticker containing the donated clothing information and attaches it to the box. The boxes containing the donated garments are placed in an input slot with a bar code recognition module and stored in a storage unit located in the lower portion of the station 30. [

Such a garbage collection PSS station 30 may be designed as a prototype including an action inducing feature. For example, the left top plate of the station 30 may be designed in appropriate height and shape to allow the apparel provider 10 to load items such as bags.

The illustrated garment collection PSS can be designed according to the PSS design method of the present invention to be described later. In addition, various PSS designs can be efficiently performed by a computer based on the PSS design method of the present invention. Hereinafter, the garment collection PSS will be described as an example for the sake of understanding.

 Figure 3 illustrates a product life cycle according to one embodiment of the present invention.

As shown in FIG. 3, a request and a requirement (hereinafter referred to as a requirement) 113 of a plurality of stakeholders 111 related to the PSS and a target value are defined. Here, the product life cycle 103 analysis process may be performed to define the potential requirement 113 of the person 111. [ That is, various potential requirements 113 may be defined through analysis of the activity of the potential associate 111 throughout the product life cycle 103 and the information of the associate 111. The related person 111 may include a service provider, a service recipient, and the like.

The product life cycle 103 analysis process may include a process of classifying the product life cycle 103, defining the related person 111, and defining the requirement 113 of the related person 111. Here, the product life cycle 103 can be classified into the pre-use step 105, the in-use step 107, and the post-use step 109. [

Subordinate steps specified for each step may be defined and arranged cyclically and sequentially, and related persons 111 may be defined for each sub-step, and may be disposed close to the node of the lower step since the degree of association is large. For reference, in FIG. 3, the related person 111 is displayed in a circular form in each step of the product life cycle 103. That is, depending on the degree of relevance, the principal associate is placed closer to the node, and the other associates are placed outside the principal associate.

For example, in the case of clothes, design, production, transportation, and the like may be included as a sub-step of the pre-use step 105, and repair, wear, storage, etc. may be included as a lower step of the in-use step 107. Subsequent steps of the post-use step 109 may include return, donation, exchange, disposal, and the like. For example, in the production phase of the pre-use phase 105, the person concerned 111, such as a garment manufacturer, fabric supplier, distributor, clothing store, etc., can be placed close to the node of the production phase, have.

The requirement 113 of the related party 111 of each lower level can be defined based on the information of the related party 111 disposed in each specified lower level. For example, when defining a demand condition 113 for a customer (customer), it is necessary to select a product / service in a pre-use step 105, Requirement conditions that desire various functions of the service, and requirements to easily discard the product / service eco-friendly in the after-use step 109 can be defined.

FIG. 4 illustrates an E3 value based value system according to an embodiment of the present invention.

Meanwhile, as shown in FIG. 4, in order to analyze what value each of the persons concerned in the PSS regards as important and to improve it to a more advanced value, the value element 203 is mutually mapped to the above- Can be defined. Here, value element 203 may include one or more of empirical value 210, economic value 220 and environmental value 230 (also referred to as " E3 value ").

For example, the empirical value 210 consists of an external value 212 and an internal value 214. The external value (212) is a value related to the functional part (213) and external sociality (215). The intrinsic value (214) consists of the emotional part (217) of self-directed and reactive aspects, internal sociality (219), and the part leading to learning and intellectual pursuit (221). Describing empirical value (210), for example, in garment collection, reactive emotions when approaching a collection that can be misinterpreted as dirty or stinky garbage cans have a negative impact on finding more garbage collectors.

On the other hand, a young mother who donates an infant 's clothing imagines that a child will wear a cute little child as cute as her child will experience proactive active emotion. In addition, if a housewife who contributes a lot of clothes records his or her donation record, it will provide external social value. The target value can be defined through a process of mapping the value elements 203 to the above-described requirements and finding a value not provided by the current garbage collection box.

Figure 5 illustrates a service blueprint for modeling pertinent behavior according to an embodiment of the present invention.

As shown in FIG. 5, a service blueprint 300 indicating a behavior modeling of an interested party may be composed of a service beneficiary layer and a service provider layer, and the service provider layer may include an on-stage on stage is a back-stage service provider layer that is not in direct contact with the service provider layer. In addition, a support process layer is added. At this time, behavior modeling based on mutual relevance of activities of related persons can be performed through a service blueprint 300 for defining and categorizing the actions of related persons and analyzing and displaying the association between the respective actions (information) have.

For example, a related person can be classified into a service receiver (SR) and a service provider (SP), and an action corresponding to each person is defined in the service blueprint 300 and displayed in a time-series manner. At this time, the association between each action is visually listed in the service blueprint 300 according to the relevance due to the interaction between the service recipient and the service provider.

For example, an act 311 of a service recipient entrusting laundry and repair may include an act 312 of an onstage service provider identifying the laundry to be repaired / cleaned and an act 312 of a washing / repairing backstage service provider 313), and the association between the corresponding actions is visually listed in the service blueprint 300. [0051] FIG.

In this manner, behavior modeling of the concerned person can be performed based on the association between the actions of the related persons displayed on the service blueprint 300. [

Figure 6 illustrates context-based behavior modeling in accordance with an embodiment of the present invention.

The actions of the related parties described above may be further elaborated through Context 450-based behavior modeling 400. That is, as shown in FIG. 6, information about activity 410, activity subject 420, object 430, tool 440, situation 450, event 460 and environment 470, for example, Element) of the person concerned can be further specified based on the action element.

Here, the act 410 includes a target element (e.g., " Package ") of the actor entity 420 and the actor entity 420 includes an active participant 421 (e.g., ), A passive associate 422 (e.g., a "Receiver") and a third party 423 (e.g., a "Guest") element. A function 431, a behavior 432, and a structure 433 are specifically included as an object element (for example, "Clothes") of the object 430 behavior And a tool 440 (e.g., a " Packaging Material ") may include elements of function 441, act 442, and structure 443 as a means for performing a goal.

In addition, the event 460 includes an element (e.g., " Prepare Donation ") that causes a change in behavior in various situations 450, (E.g., " Clothes TakeIn / CVS Structure "), a physical situation 453 (e.g., (E.g., "Daytime / Noisy / Bright") and psychological conditions 454 (eg, "Pleasant / Safe") . In addition, the environment 470 in which the action takes place may include an inner space 471, an outer space 472, and a virtual space 473.

For example, a physical situation (453), a physical situation (453) where a garbage collection box is located in a secluded alley (453), a psychological situation (454) disliking walking alone, Let's suppose a housewife is placed on. In this situation, the empirical value of donation will not be positive. On the other hand, if you replace each element of the situation with another, you can create a more positive experience of action.

Various scenarios can be created based on the above-described context-based behavior modeling 400, which will be described below with reference to FIG.

FIG. 7 illustrates a scenario creation template according to an embodiment of the present invention.

As shown in FIG. 7, various scenarios may be created by interconnecting behavior concepts 510 that change the state of each behavior 520 of a related person through a scenario creation template 500.

That is, each behavior 520 has an action concept 510 based on another context, and it is possible to create a scenario by selecting a particular behavior concept 510 from each behavior 520 and concatenating (or combining) do. Accordingly, the modeling of the new behavior can be performed through the generation of a scenario composed of sequential mapping of various behaviors, and the behavior indication scheme according to the situation can be implemented through the scenario creation template 500.

8 and 9 illustrate PSS functional modeling according to an embodiment of the present invention.

8 and 9, the PSS function modeling 600 defines upper associates 610 and 620 mapped to the higher and upper functions of the PSS implementing the requirements and the target value, The upper associates 610 and 620 are divided into one or more sub-associates 612 and 622 mapped to the lower and lower functions. Here, the function of implementing the target value and the definition of the related person can be performed from the process of generating the scenario described above. This simplifies the PSS functional modeling 600 and effectively integrates partial solutions.

More specifically, in the PSS function modeling 600, a service includes a service function, a service provider, a beneficiary of a service, and an input / output element. Thus, a higher service provider defined as a higher related party 610, 620, The information of the service recipient can be appropriately displayed in the upper functional block 601 indicating the higher functionalities.

Further, the flow class of energy, material and information as input / output elements is displayed in the upper functional block 601 together with information of the upper service provider and the upper service beneficiary. Here, the input / output elements indicate a logical connection between functional blocks. For example, the service provider and the service beneficiary may be displayed in the form of a folded line at the upper left corner and the lower right corner of the upper functional block 601. [

Also, as shown in FIG. 9, since the parent function is divided into one or more child functions based on each function (information), the divided child service providers and the child service beneficiaries are appropriate for the child functional blocks 602 to 605 Respectively.

At this time, the lower functional blocks 602 to 605 are grouped based on the logical connection structure of the flow class which is an input / output element or the relation of the lower service provider and the lower service beneficiary disposed in the lower functional blocks 602 to 605, B '), and the lower functional blocks 602 to 605 grouped (A', B ') can be used to define the PSS functional blocks.

FIG. 10 is a three-dimensional view of a function-linked service blueprint by adding a function layer according to an embodiment of the present invention, and FIG. 11 is a two-dimensional view of a function-linked service blueprint.

It is possible to map the actions and functions of the above-mentioned related persons and related persons, and map the product elements and the service elements to each other based on the correlation, thereby generating the PSS concept idea. That is, the service provider and the service recipient corresponding to the above-mentioned lower function are mapped, and the sub-actions of the service provider and the sub-actions of the service recipient are mapped to each other. Then, the PSS concept concept can be generated by mapping the sub-functions and sub-activities based on the information of the service provider and the service recipient, and mapping product elements and service elements performing the sub-functions to the corresponding sub-functions.

At this time, each function, related person and action may be further divided into one or more, and each element of the lowest level may be interconnected to the product element and the service element to create a specific PSS concept. In addition, the mapping between sub-functions and sub-activities can be made through the relevant information, and product elements and service elements can be assigned to sub-functions for creation and presentation of PSS concepts.

Describing in substantial detail, for example, the function of garment collection is modeled as an overall concrete function of delivering already used garments in a donor's home to a beneficiary in a certain way, in a usable state. Depending on the modeling, the garbage collection system should provide the ability to move garbage collected to the appropriate storage bin to the appropriate storage space. In this way, the functionality of the overall garment collection based on the garbage collection box currently in the neighborhood alley can be modeled as a plurality of sub-functions. Here, a product element and a service element that perform a lower function can be mapped, and a function and a behavior of a related person are mapped by connecting an action on a service blueprint through information of a related person mapped to a lower function.

Thus, with the basic functions and behaviors identified, it becomes possible to design new functions or behaviors to achieve the value elements defined by the target value. For example, when the function of mapping the dimension and material information related to the donated clothes to the donated garment is added, it is possible to provide the donation apparel suited to the demand of the apparel beneficiary so that the value of the functional experience, This is the reason for the increase of the emotional value.

At this time, as shown in Figs. 10 and 11, the service blueprint 301 may be used to display the PSS concept. Here, the function layer 340 inserted between the service beneficiary (e.g., clothing donor, beneficiary) layer 310 and the onstage service provider (e.g., a laundry / repair shop, a beneficiary management company, etc.) layer 320, May be displayed on the service blueprint 301. At this time, the function layer 340 may function as a layer for mapping the inter-related actions 311, 321, and 331 and the function 341.

The interaction relationship between the behavior 331 of the backstage service provider (e.g., donor company, collection company, disposal company, etc.), the behavior 321 of the onstage service provider, and the behavior 311 of the service recipient is the service blueprint ≪ / RTI > 301).

This makes it possible to clarify the specific functional objectives of the service recipient's actions and the service provider's actions. In other words, it is possible to analyze the inter-action interactions to implement concrete objective values and display the corresponding different service blueprints 301 in a plurality of PSS concepts.

The above-described PSS concept annotation can be further described in the service blueprint 301 by mapping product elements and service elements with various external stakeholders. If the PSS concept idea for the garment "production" step is derived in the product lifecycle of FIG. 3 described above, the manufacturer, fabric supplier, distributor, clothing store, etc., besides the service provider and service recipient, may be external parties. At this time, internal relevance between product elements and service elements can be analyzed and defined, as well as relevance to external stakeholders. In order to specify the PSS concept, the product element, the service element, and the restriction condition corresponding to each action of the service provider are defined, and the PSS concept specified based on the sequential order of the actions related to the product element and the service element You can determine the order of operations.

Next, a prototype in the PSS concept can be defined by performing a simulation test based on the operating sequence in the materialized PSS concept. Specifically, you can define PSS prototyping and behavior and the PSS scenarios that are relevant to you, and define the PSS concept prototypes through PSS operation simulation.

At this time, the above-described materialized PSS concept is implemented as a provisional PSS prototype. Here, the PSS prototype may be a scenario reflecting the physical structure or important functional requirements and attributes, and the PSS concept may be tested and evaluated through simulation to meet the needs and values of a particular service recipient.
