“…Beberapa penelitian telah mengembangkan sistem informasi manajemen inventaris/aset, yang mana sistem yang dikembangkan tersebut memuat menu-menu mengenai kegiatan perbekalan (Taleizadeh et al, 2020), (Bartoszewicz and Latosiński, 2019), (Cendani et al, 2019), (Dharma et al, 2019), (Rachmawati et al, 2018), (Tejesh and Neeraja, 2018), (Pambudi et al, 2017), (Atieh et al, 2016), (Mirzaei and Seifi, 2015), (Pertiwi et al, 2013). Akan tetapi, pengembangan sistem informasi manajemen inventaris/aset pada penelitian sebelumnya terbatas untuk diterapkan di instansi swasta baik perusahaan atau kantor-kantor tertentu.…”

Perkembangan Teknologi Informasi dan Komunikasi (TIK) telah berpengaruh terhadap penggunaan media pembelajaran dimana pendidik dituntut kreatif dalam memanfaatkan teknologi yang berkembang. Oleh karena itu, penelitian ini bertujuan untuk menghasilkan produk media pembelajaran berbasis website untuk meningkatkan keterampilan praktikum mahasiswa. Kini di tengah wabah pandemi covid-19, produk berupa media pembelajaran yang dikembangkan ini dapat menjadi alternatif pilihan dalam pelaksanaan pembelajaran secara daring. Model penelitian dan pengembangan ini menggunakan model Research and Development Borg and Gall yang telah dimodifikasi. Teknik analisis data yang digunakan adalah deskriptif persentase dan Uji Independent Sample t-Test. Hasil penelitian dan pengembangan ini adalah Sistem Inventarisasi Barang (SIMVERA) sebagai media pembelajaran pada mata kuliah manajemen perbekalan dengan menyajikan menu-menu terkait kegiatan perbekalan dalam ruang lingkup yang luas meliputi data supplier, data inventaris, data ruangan, data peminjaman, data pengembalian, data pelaporan hingga prosedur penghapusan barang. Selain itu, sistem SIMVERA ini juga dilengkapi dengan QR Code yang dapat diterapkan saat terjadi ketidaksesuaian terhadap barang inventaris. Sistem SIMVERA ini telah dinyatakan sangat valid dan layak digunakan dalam pembelajaran khususnya dalam kegiatan praktikum inventaris barang oleh ahli media, ahli materi, dan 6 mahasiswa uji coba kelompok kecil serta terbukti dapat meningkatkan keterampilan praktikum mahasiswa secara signifikan pada uji coba kelompok besar. Sehingga dapat disimpulkan bahwa Sistem Inventarisasi Barang (SIMVERA) layak dan efektif digunakan sebagai media pembelajaran pada mata kuliah manajemen perbekalan untuk meningkatkan keterampilan praktikum mahasiswa.

“…Vladimir et al [ 23 ] considered the optimization problem of a failure-prone manufacturing system with uncertainty in demand and inventory levels, and designed a controller based on adaptive control for the online estimation and optimal control of a supply-chain inventory system in the presence of unknown demand and inaccurate inventory. Bartoszewicz et al [ 24 ] used sliding mode control to optimize the management of manufacturers’ inventories with storage constraints for manufacturers’ inventory management under different demands. Achamrah et al [ 25 ] used the genetic algorithm and deep reinforcement learning to solve the inventory path problem with transit and substitution under dynamic and stochastic demand.…”

Aiming at the real-time robust optimization problem of perishable supply-chain systems in complex environments, a real-time robust optimization scheme based on supply-chain digital twins is proposed. Firstly, based on the quantitative logical relationship between production and sales of single-chain series supply-chain system products, the state space equation of the supply-chain system with logical characteristics, structural characteristics, and quantitative characteristics was constructed, and twin data were introduced to construct the digital twins of supply chains based on the state-space equation. Secondly, the perishable supply-chain system in complex environments was regarded as an uncertain closed-loop system from the perspective of the state space equation, and then a robust H∞ controller design strategy was proposed, and the supply-chain digital twins was used to update and correct the relevant parameters of the supply-chain system in real-time, to implement the real-time robust optimization based on the supply-chain digital twins. Finally, the simulation experiment was carried out with a cake supply-chain production as an example. The experimental results show that the real-time updating of relevant parameters through the digital twins can help enterprise managers to formulate reasonable management plans, effectively avoid the shortage problem of enterprises in the cake supply-chain system, and reduce the maximum inventory movement standard deviation of each link by 12.65%, 6.50%, and 14.87%, and the maximum production movement standard deviation by 70.21%, 56.84%, and 45.19%.

Bu çalışmanın ilgilendiği konu, hammaddelerin hangi raf alanına atanacağına karar verilmesi ve maksimum miktarda atanmasıdır. Bu karar verilirken, alanın sınırlı olduğu, tüm hammaddelerin kendi aralarında aynı önem seviyesine sahip olmadığı, farklı stok ve palet büyüklüğüne sahip olduğu düşünmelidir. Mevcut çalışmalarda, raf boyutları ve paletler tek boyutlu veya standart ölçülerle hesaplanmaktadır. Ancak, gerçek hayatta raf ve palet boyutları genişlik, yükseklik ve derinlik açısından farklı ölçülere sahiptir. Bu çalışmadaki gerçek uygulamada, tüm durumların matematiksel modeli oluşturulmuştur. Çalışmada kurulan model, önem derecelerine göre optimum miktarların atandığını göstermektedir. Öncelikle ABC analizi kullanılarak A sınıfındaki hammaddeler belirlenmiştir. Çok kriterli karar verme yöntemi ile bu hammaddelerin önem katsayıları belirlenmiş ve doğrusal modelin amaç fonksiyonu oluşturulabilmesi için ana kriterler 4 farklı uzmanın hammaddeleri sınıflandırabileceği şekilde belirlenmiştir. Uzmanların sahip olduğu farklı görüşleri ve hammaddeler için belirlenen kriterler arasındaki ilişkileri göz ardı etmeden model oluşturmak için Bulanık Analitik Ağ Prosesi (Bulanık AAP) kullanılmıştır. Matematiksel modelin kısıt denklemleriyse blok raf sistemlerine ait hücrelerin değişen kapasiteleri ve hammaddelerin maksimum-minimum stok değerlerine göre oluşturulmuştur. Sonuç olarak, hangi rafta hangi hammaddenin ne kadar tutulacağının belirlenmesi ile depo görevlisi yönlendirilmiştir.
