Fuzzy graphs are the backbone of many real systems like networks, image, scheduling, etc. But, due to some restriction on edges, fuzzy limited represent for systems. Generalized appropriate avoid such restrictions. In this study generalized introduced. study, matrix representation is described. Completeness and regularity two important parameters graph theory. Here, regular complete Some properties them discussed. After that, effective exemplified.

Time series data are prevalent in diverse fields such as manufacturing and sensor-based human activity recognition. In real-world applications, these often collected with variable sample lengths, which can pose challenges for classification models that typically require fixed-length inputs. Existing approaches either employ designed to handle input sizes or standardize lengths before applying models; however, we contend may compromise integrity ultimately reduce model performance. To address...

Abstract Lithium (Li) metal is widely acknowledged as the most promising anode material, owing to its high capacity and low potential. However, practical implementation of Li faces challenges, including uncontrollable dendritic growth a deficient solid electrolyte interphase (SEI). Here straightforward method provided for fabricating composites using Al‐doped 7 La 3 Zr 2 O 12 particles (Li/LLZO) with Li‐ion conductivity achieved mechanical kneading process. The optimized composite, 20% LLZO...

The paper deals with an integrated inventory model make-to-order policy from buyer to vendor. A variable transportation cost is used as a power function of the delivery quantity for either tapering or considering proportional rate data maintain single-setup multi-delivery (SSMD) reduced cost. two-stage inspection process introduced by vendor ensure perfect quality product even though first indicates constant defective imperfect production present during long-run system and all items are...

Modelling complex systems poses significant challenges on how one represents the system components and interactions among them. In order to provide a systematic approach represent human participation as part of dynamic system, this paper presents formal automata model human-machine cooperative that incorporates capabilities with respect conditions. Specifically, we propose control for human-involved shop floor based discrete event-based (DES) an environmental concept known affordance. When...

Quality function deployment (QFD) was initially developed to aid in designing a quality product by interconnecting customer needs market segment with technical requirements (TRs). It can assist improving but does not have examine TRs across the major segments serviced company's lines and developing modular platform concept. In this paper, we present concept development method that aids as well an understanding of family design. This is conducted three steps. The first step identify from QFD...

Separators play an essential role in lithium (Li)-based secondary batteries by preventing direct contact between the two electrodes and providing conduction pathways for Li-ions battery cells. However, conventional polyolefin separators exhibit insufficient electrolyte wettability thermal stability, particular, they are vulnerable to Li dendritic growth, which is a significant weakness Li-metal (LMBs). To improve safety electrochemical performance of LMBs, Al2O3 nanoparticles nanocellulose...

This paper develops two centralised two-echelon supply chain models with the trade-credit financing and inspection errors. Both follow a single-setup-multi-delivery (SSMD) policy each delivery is designed using just-in-time (JIT) method to increase efficiency of chain. In first model, random defective rate assumed delivered item goes through process at buyer's end due contract vendor, because vendor gives support buyer. second human errors Type I II are considered tiredness ignorance...

This paper describes a human–automation interactive manufacturing system and presents formal model for describing controlling the system. The presented in this considers from two perspectives: structural operational perspectives. Human an automated controller are considered agents that cooperate to achieve given goals by executing assigned tasks. A interaction is described with particular communication between exchanges messages. control schema human tasks modelled separately then integrated...

Human-machine interaction is one of the most crucial aspects advanced manufacturing systems that have to so-called smart systems. In this regard, paper presents a framework for formalizing human-machine The system considered in consists following three main components: human supervisor; several cells, each which composed operator and machine; interfaces. A interacts with machine cell performs tasks based on commands given by supervisor. Meanwhile, supervisor responsible performing exception...

As unmanned aerial vehicles have become popular, the number of accidents caused by an operator’s inattention increased. To prevent such accidents, operator should maintain attention status. However, limited research has been conducted on brain-computer interface (BCI)-based system with alerting module for recovery vehicles. Therefore, we introduce a detection and that prevents vehicle from falling into status using electroencephalogram signal. The proposed consists following three...

Abstract Real-time monitoring for Additive Manufacturing (AM) processes can greatly benefit from spatial-temporal modeling using deep learning. However, existing, deep-learning approaches in AM are case-dependent, and therefore not robust to changes of control inputs data types. As is dynamic complex, this limitation leads a lack systematic, DL real-time AM, which involves large number varying parameters data. To address the challenge, paper introduces novel approach developing models...

With the advance of military technology, number unmanned combat aerial vehicles (UCAVs) has rapidly increased. However, it been reported that accident rate UCAVs is much higher than manned vehicles. One main reasons for high hypovigilance problem which refers to decrease in vigilance levels UCAV operators while maneuvering. In this paper, we propose detection models based on EEG signal minimize occurrences hypovigilance. To enable detection, have applied hidden Markov (HMMs), two are used...

This paper presents a formal approach to resolve an important question concerning changes in the control of computerized manufacturing systems when human operator is involved as task-performing agent.
