Modeling the use of voice based assistant devices (VBADs): A machine learning base an exploratory study using cluster analysis and correspondence analysis

There is a growing prevalence of Voice-Based Assistant Devices (VBADs) in our urban lives. The unique and lively user and interaction experience offered by this smart and Artificial Intelligence (AI) enabled device, not only helps to serve a variety of functions for its users but also provides them companionship to relieve the boredom. The present study attempts to explore the various describing words or phrases that the users of VBADs often use describing them, by making use of the projective word association technique. Post this using the cluster analysis the study has aimed to probe into the usage intentions of the users regarding these devices, examining if these are used for purely functional purposes or are also capable of meeting some kind of friendly relationship bond with their users. The cluster analysis was performed using machine learning and mathematical modeling. Further, the study explores a perceptual brand mapping for a few popular brands of VBADs using correspondence analysis, to understand if these brands have more points of parity in common or are they distinct across each other. The findings indicate that besides meeting the regular functional goals for the people, these devices also bond with the people by becoming their partners, friends, or members of the family. There exists a distinction across brands studied, where though all the brands satisfied their users by serving different functional purposes, however only Google Assistant and Alexa were capable of forming relational ties with their users. The brands engineering these devices can essentially base their product development and user interaction model taking the findings of this study into consideration for improving the future user experience.

A wholistic optimization of containerized workflow scheduling and deployment in the cloud–edge environment

Digital Twin in Industry 4.0 utilizes Internet of Things (IoT) to collect real-life data and combine it with simulation models for product design and development. The simulation process can be executed as a workflow, consisting of tasks with precedence constraints. In a container-based workflow execution system, each task in the workflow is executed in a container within a virtual machine (VM). In this paper, a three-step scheduling model is proposed to combine scheduling of container-based workflows and the deployment of containers on a cloud–edge environment. In the first step, virtual CPU (vCPU) is allocated for each container to enable vCPU sharing among different containers. Next, two-step resource deployment is used to schedule the containers onto VM, and VM onto the physical machines in either edge or cloud environment. Multiple objectives are considered, including minimizing makespan, load imbalance, and energy consumption, from the perspective of cloud–edge resources as well as containerized workflows. To obtain a set of non-dominated solutions, three evolution strategies are designed and combined with two multi-objective algorithm frameworks — co-evolution strategy (CES), basic non-co-evolution strategy (B-NCS), and hybrid non-co-evolution strategy (H-NCS). Simulation results demonstrate that the proposed model outperforms the existing two-step scheduling model and H-NCS performs better than other strategies.

Reducing the Total Product Cost at the Product Design Stage

Currently used decision support systems allow decision-makers to evaluate the product performance, including a net present value analysis, in order to enable them to make a decision regarding whether or not to carry out a new product development project. However, these solutions are inadequate to provide simulations for verifying a possibility of reducing the total product cost through changes in the product design phase. The proposed approach provides a framework for identifying possible variants of changes in product design that can reduce the cost related to the production and after-sales phase. This paper is concerned with using business analytics to cost estimation and simulation regarding changes in product design. The cost of a new product is estimated using analogical and parametric models that base on artificial neural networks. Relationships identified by computational intelligence are used to prepare cost estimation and simulations. A model of product development, production process, and admissible resources is described in terms of a constraint satisfaction problem that is effectively solved using constraint programming techniques. The proposed method enables the selection of a more appropriate technique to cost estimation, the identification of a set of possible changes in product design towards reducing the total product cost, and it is the framework for developing a decision support system. In this aspect, it outperforms current methods dedicated for evaluating the potential of a new product.

МОДЕЛЬ ОРГАНИЗАЦИИ РАЗРАБОТКИ ЭКСТРУЗИОННЫХ 3D-ПРИНТЕРОВ

A model of innovative product development based on a process approach and characterized by taking into account feedbacks between the stages of product creation and the mutual influence of the products being developed within one stage is presented.Each product is characterized by a variety of internal quality parameters X. As the product development process progresses, the values of quality parameters are changed within each stage. At the entrance, the transition between stages and the exit from the funnel, there are barriers to assessing the quality parameters of X products.The proposed model and calculation formulas make it possible to organize work to improve the efficiency of the product creation process, in particular, to assess the distribution of developments by stages, including the search for the optimal number of stages, the maximum period of finding and requirements for the transition of development to the next stage.On the basis of this mathematical model, using AnyLogic software, calculations of the dynamics of the passage of the product at each stage of development were carried out. The process of developing an extrusion 3D printer includes 5 stages: development and development of an idea, development of a 3D printer working chamber, development of an extruder, development of 3D printer electronics, prototype development. The initial data for the calculations were provided by the LLC "Company IMPRINTA", which is engaged in the development, manufacture and sale of Hercules brand 3D printers. As a result of the simulation, a graph of the total number of developments received at each stage was obtained. To optimize the process of creating new products, the corresponding AnyLogic module was used. The possibilities of optimizing the current structure of the organization of 3D printer development in the LLC "Company IMPRINTA" are considered. Two directions of optimization are proposed: reducing the number of excluded projects by selecting the required minimum load of each stage and the maximum time spent on the development stage; increasing the number of successful developments by selecting the minimum requirements for each stage and the intensity of incoming developments at the entrance to the funnel. It was possible to reduce the number of excluded developments by 30%.

Development and Proof-of-Concept Evaluation of a Sensory Science-Based Model for Product Development of Vegetable-Based Products for Children.

Children’s vegetable intake is too low, and a key barrier to the inadequate intake is low acceptance. To facilitate successful development of new vegetable-based products for children, a sensory science approach to product development has been taken. A new theoretical model is proposed, the CAMPOV model: Children’s Acceptance Model for Product development of Vegetables. The model is informed by scientific literature and considers biological, psychological, and situational, and intrinsic and extrinsic product factors relevant to children’s acceptance of vegetables, with a focus on modifiable factors at the product level. Simultaneously, 14 new vegetable-based product concepts for children were developed and evaluated through focus groups with 5–8-year-olds (n = 36) as a proof-of-concept evaluation of the model. Children had high interest in six of the concepts. Factors identified from the literature that positively associated with the children’s interest in the concepts included bright colours, bite-sized pieces, good taste, fun eating experience, and familiarity. The CAMPOV model and proof-of-concept evaluation results can guide further sensory and consumer research to increase children’s acceptance of food products containing vegetables, which will in turn provide further insights into the validity of the model. The food industry can use the model as a framework for development of new products for children with high sensory appeal.

SUBSTANTIATION OF DEVELOPMENT STAGES OF THE INFORMATION SYSTEM FOR SUPPORT OF TESTS OF ARMAMAENT AND MILITARY EQUIPMENT OF THE ARMED FORCES OF UKRAINE

One of the important areas of support and development of the state's defense capabilities is to equip the armed forces with modern armament and military equipment (AME). In recent years, due to the situation in eastern Ukraine, there has been a significant increase in the pace of development and adoption of the newest models of AME. The process of harmonizing national standards with NATO standards also contributes to this. Naturally, it causes an increase in the need for timely and high-quality testing of AME samples. Accordingly, the task of improving the efficiency of all processes that accompany the testing of defense products is urgent.
 The article considers the problem of practical development of information system for support of tests of AME, the purpose of which is to automate information processes in the preparation and conduct of tests, which should reduce time and labor costs at all stages of testing. Based on the previously substantiated spiral model of software product development and the concept of building an information system for test support, a step-by-step plan for the implementation of the information system is proposed.
 The system of requirements to the prototype of the information system with limited functionality is formulated, according to which the rating estimation of need and possibility of prioritized realization of the basic functional modules of the information system is carried out. Based on the requirement of functional connectivity of the modules, the information system composition on the next turn of the life cycle spiral model is substantiated. The step-by-step approach during creation and provisioning of databases and data registers with information are considered. As the information system develops, the transition to an incremental model of software product development is not excluded.
 It is expected that the automation of information processes related to the planning and conducting of tests, as well as the processing of test results and preparation of reporting documentation can positively impact the overall efficiency of the organization and conducting of tests, as well as ensure the proper quality of results.

A New Product Development Model for SMEs: Introducing Agility to the Plan-Driven Concurrent Product Development Approach

In order to survive in today’s highly competitive global market, small and medium-sized enterprises (SMEs) have had to transition from sequential to concurrent product development, which significantly shortens development cycles, reduces costs, and ensures high product quality. Despite its many benefits, concurrent product development is still based on detailed upfront planning and cannot address the challenges related to today’s ever-growing uncertainty, constantly changing environment, and unstable requirements. A potential solution to this problem could be in more flexible and value-driven agile project management (APM) approaches, typical of software development. In this paper, we propose a new product development model specifically appropriate for SMEs that combines concurrent product development principles with APM elements. It is designed as a loop of five repetitive steps (macroplan, microplan, iteration activities, review, and retrospective) that are being executed within individual concurrent development loops. The application of the model is presented on a real case example of process development and small batch manufacture of a complex wiring harness. The study reveals many benefits of the proposed model, such as improved communication, faster detection of discrepancies, more effective problem solving, and greater flexibility. A positive impact on project success is also observed.

When to Be Agile: Ratings and Version Updates in Mobile Apps

Lean and agile models of product development organize the flexible capacity to rapidly update individual products in response to customer feedback. Although agile operations have been adopted across numerous industries, neither the benefits nor the factors explaining when firms choose to become agile are validated and understood. We study these questions using data on the development of mobile apps, which occurs through the dynamic release of new versions into the mobile app marketplace, and the apps’ customer ratings. We develop a structural model estimating the dependence of product versioning on (a) market feedback in the form of customer ratings against (b) project and work-based considerations, such as development timelines, scale economies, and operational constraints. In contrast to when they actually benefit from operational agility, firms become agile when launching riskier products (in terms of uncertainty in initial customer reception) and less agile when they are able to exploit scale economies from coordinating development over a portfolio of apps. Agile operations increase firm payoffs by margins of 20% to 80%, and interestingly, partial agility is often sufficient to capture the bulk of these returns. Finally, turning to a question of marketplace design, we study how the mobile app marketplace should design the display of ratings to incentivize quality (increasing app categories’ average user satisfaction rates by as much as 22%). This paper was accepted by Jayashankar Swaminathan, operations management.

COMPARISON OF SOFTWARE METRICS FOR QUALITY ESTIMATION OF THE SOFTWARE PRODUCTS

There is a well known principle, that you can manage only what you can measure – therefore adequate measurement and estimation of different elements in any engineering area is a very important development factor, and software engineering is not an exception. Software metrics represent numeric values of software characteristics and are used for analysis of different aspects of the product in order to predict possible problems. Software metrics can be applied to any stage of the software life cycle. For instance, on a stage of requirement analysis and the problem formulation, these metrics help to estimate the required amount of work and, respectively, the amount of financial and work resources. In addition, the metrics can be used directly in estimation of the program code complexity to assess it’s performance, effectiveness and the ability to modify it if needed. Software metrics are an important part of the whole software quality management process as they can be easily automated and applied in order to achieve some valuable technical characteristics. Moreover, they can be combined with another quality management tools and are a beneficial addition to any software product development model. In general, measuring the attributes of software during any phase of development gives a number of beneficial results to the developers as it helps to use the time, finances and effort effectively. This is achieved because of early problems identification, estimation and prevention and because of that the size, cost, quality and simplicity of the maintenance of the product is always under control. This article describes the results of research on different software metrics types and the actual representatives of these types. It assesses the usage area and the convenience of it’s usage on evaluating the quality of both a finished product and a product in the development stage.

TU73. GENETIC LIABILITIES OF SCHIZOPHRENIA RISK FACTORS AS POLYGENIC SCORES FOR CASE STATUS PREDICTION: APPLICATION AND BIAS EVALUATION IN A MULTI-ANCESTRY SETTING

Cloud-Based Design and Manufacturing is a service-oriented networked product development model in which service consumers are enabled to configure, select and utilize customized product realization services ranging from computer-aided engineering software to reconfigurable manufacturing systems. So far, this paradigm has mainly been tested for digital design and fabrication processes including the usual steps of designing an artefact with a CAD system to then have a prototype manufactured with a 3D printer. Unfortunately, a common mishap that can often be observed is that artefacts that look perfectly fine on the CAD computer screen come out severely misshaped on the 3D printer. In this paper, we first investigate and document this phenomenon and explain its root cause, which concerns a) the data transmitted to the 3D printer, b) inappropriate design features, and c) a mismatch between geometry requirements and printer capabilities. As more and more entrepreneurs, hobbyists in maker communities, and other not always fully trained individuals pursue their design and make ideas, there is a need for smart computer-based support to facilitate a successful design-to-print process. Such a digital DfM assistant might pop up to prompt a designer to modify identified critical areas of the design so that it can be printed with a chosen printer or alternatively propose another type of printer that may have the technical capabilities to accommodate the design in its current form. Acknowledging this need, we propose a two-stage smart manufacturability assistant. The first stage decomposes the digital model into a series of part features; the second stage of the model involved defining the capabilities of the 3D-printer. Finally, we begin to realize this manufacturability assistant by creating and evaluating a bespoke test part which can be used to define a machine-material capability map for an example FDM process.

Unravelling the design process of business models from linear to circular: An empirical investigation

AbstractIn the last years, circular economy has represented one of the most‐debated topics in management research. Although the understanding of this industrial paradigm has significantly improved over the last decade, a number of important research questions still remain unanswered. Among them, the design process of business model through which established firms evolve from being linear to circular deserves further investigation. Existing research still falls short to investigate how companies design the dimensions of value creation, value transfer, and value capture of their business models to launch circular products into the market. By leveraging a multiple case study analysis of four companies in the paper and beverage industries that have launched six circular products, the paper examines the process that these companies have followed to face the transition toward a circular business model. The paper contributes to the research field in the intersection between new product development and circular business models, by showing that the process toward a circular business model occurs along three major phases, that is, idea generation, product development, and commercialization. In each phase, companies implement peculiar managerial practices for launching circular products into the market, which typically address all the dimensions of the business model and follows a recurrent path over time.

Research on the Evaluation of Customer requirement Importance of Smart Products Based on Online Comments and Improved Quantitative Kano Model

With the development and popularization of smart products, the technological differences of products are decreasing, and the phenomenon of product homogeneity is becoming more and more obvious. It is necessary for the smart product manufacturing firms have the capability to analyze customer requirement deeply and adapt to the dynamically changing market quickly. Therefore, the traditional technology-oriented product development model is no longer suitable for manufacturers to obtain a competitive advantage. Based on this, this paper proposed a method to evaluate the importance of customer demands based on online comments and quantitative Kano model. First, the Python crawler tool is used to obtain online customer reviews of relevant products and the word segmentation processing is performed to obtain the product features and frequency that customers are mainly concerned about, and then the initial importance of demand can be calculated. Furthermore, use the quantitative Kano model to determine the customer satisfaction and revise the initial importance of the requirements to obtain a more reasonable ranking of the importance of user needs. Finally, a case study is carried out with the smart bracelet as an example to verify the effectiveness and feasibility of the model proposed in this paper.

PRODUCT REQUIREMENTS SPECIFICATION PROCESS IN PRODUCT DEVELOPMENT

AbstractRequirements engineering and requirements management are essential sub-processes of product development and are an integrated part of virtually all product development models and industrial process descriptions. Proprietary and context specific processes for working with requirements are used in industrial design practice. However, these are not appropriately reflected in existing process models for product development. Existing standards describe the content and generation of requirements documents but not their integration in the product development process.The study is based on a retrospective analysis of a set of representative real-world product development projects from automotive industry and rail industry. Comparing the processes downstream the milestone “release of PRD”, it was found that subsequent processes to manage requirements and specifications do not differ much with regard to industrial context. Based on this, a model for the product requirements specification (PRS) process is proposed which addresses the gap.
